==================================================================================
Date API Installation instructions:
==================================================================================
1) If you have an earlier version of the Date module on your system, empty the
date folder out completely. The files in version 2 have different names and are
located in different places.
2) Download the whole package of files from http://drupal.org/project/date.
3) Upload the date files to the modules directory. The package includes files
needed by the Date API, and optional modules to to create CCK date fields.
4) Go to admin/build/modules and enable the needed modules from the Date/Time group.
You should end up with a structure like:
/drupal/sites/all/modules/date/date_api.info
/drupal/sites/all/modules/date/date_api.install
/drupal/sites/all/modules/date/date_api.module
...
/drupal/sites/all/modules/date/date/date.info
/drupal/sites/all/modules/date/date/date.install
/drupal/sites/all/modules/date/date/date.module
...
/drupal/sites/all/modules/date/date_copy/date_copy.info
/drupal/sites/all/modules/date/date_copy/date_copy.module
...
/drupal/sites/all/modules/date/date_php4/date_php4.inc
/drupal/sites/all/modules/date/date_php4/date_php4_lib.inc
...
==================================================================================
Older PHP versions
==================================================================================
If you are using PHP 4 or PHP 5.0 or 5.1, native date handling won't work right.
Install the Date_PHP4 module to enable wrapper functions so this code will work
in old PHP versions.
==================================================================================
Enable Date Timezone
==================================================================================
In most cases, you should enable the Date Timezone module any time you use the
Date API to be able to set the site and user timezone names. It is not enabled by
default in case another module is setting timezone names in the database.
Once you have enabled it, go to admin/settings/date-time and set the default
site timezone name. If you are using user timezones, go to your account settings
and set up your own timezone name.
==================================================================================
Install CCK Date Fields:
==================================================================================
1) The CCK date field is included in the Date files at http://drupal.org/project/date.
2) Go to admin/build/modules and enable the Date module. Be sure that the Date API module,
the Date Timezone module, and the Content module are also installed.
3) Go to admin/content/types to view cck content types and edit a content type.
4) Make sure the default timezone name has been set at admin/settings/date-time.
5) While viewing a content type, select the option to add a new field from the tabs at
the top of the page. Several options for date fields should be visible.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

INFORMATION FOR DEVELOPERS
Once the Date API is installed, all functions in the API are available to be used
anywhere by any module. If the Date Timezone module is installed, the system site
timezone selector and the user timezone selectors are overwritten to allow the
selection of timezone names instead of offsets. Proper timezone conversion
requires knowledge of those timezone names, something that is not currently
available in Drupal core, and the change in selectors makes it possible to track it.
In most cases, you should enable the Date Timezone module any time you use the
Date API to be able to set the site and user timezone names. It is not enabled by
default in case another module is setting timezone names in the database.
The API uses the PHP 5.2 date functions to create and manipulate dates, and
contains an option module that will emulate those functions in earlier versions
of PHP.
If you are using PHP 4 or PHP 5.0 or 5.1, native date handling won't work right.
Install the Date_PHP4 module to enable wrapper functions so this code will work
in old PHP versions.
Example, the following will create a date for the local value in one
timezone, adjust it to a different timezone, then return the offset in seconds
in the new timezone for the input date; The offset will be adjusted for both
the timezone difference and daylight savings time, if necessary:
$date = date_create('2007-03-11 02:00:00', timezone_open('America/Chicago'));
$chicago_time = date_format($date, 'Y-m-d H:i');
print 'At '. $chicago_time .' in Chicago, the timezone offset in seconds
was '. date_offset_get($date);
date_timezone_set($date, timezone_open('Europe/Berlin');
$berlin_time = date_format($date, 'Y-m-d H:i');
print 'It was '. $berlin_time .' in Berlin when it
was '. $chicago_time .' in Chicago.';
print 'At that time in Berlin, the timezone offset in seconds was
'. date_offset_get($date);
A helper function is available, date_make_date($string, $timezone, $type),
where $string is a unixtimestamp, an ISO date, or a string like YYYY-MM-DD HH:MM:SS,
$timezone is the name of the timezone this date is in, and $type is the type
of date it is (DATE_UNIX, DATE_ISO, or DATE_DATETIME). It create and return
a date object set to the right date and timezone.
Simpletest tests for these functions are included in the package.
Available functions include the following (more documentation is provided in
the files):
============================================================================
Date PHP4 Module
============================================================================
PHP 4 substitutions for the PHP 5 date functions are supplied. Use the PHP 5
functions in your code as they would normally be used and the PHP 4
alternatives will be automatically be substituted in when needed.
You cannot do everything with these functions that can be done in PHP 5, but
you can create dates, find timezone offsets, and format the results.
Timezone handling uses native PHP 5 functions when available and degrades
automatically for PHP 4 to use substitutions like those
provided in previous versions of the Date and Event modules.
Read the doxygen documentation in this module for more information
about using the functions in ways that will work in PHP 4.
Simpletest tests for the PHP 4 equivalent functions are included in the package.
The following functions are emulated in PHP4:
date_create()
date_date_set()
date_format()
date_offset_get()
date_timezone_set()
timezone_abbreviations_list()
timezone_identifiers_list()
timezone_offset_get()
timezone_open()
============================================================================
Preconfigured arrays
============================================================================
Both translated and untranslated values are available. The date_week_days_ordered()
function will shift an array of week day names so it starts with the site's
first day of the week, otherwise the weekday names start with Sunday as the first
value, the expected order for many php and sql functions.
date_month_names();
date_month_names_abbr();
date_month_names_untranslated();
date_week_days();
date_week_days_abbr();
date_week_days_untranslated();
date_week_days_ordered();
date_years();
date_hours();
date_minutes();
date_seconds();
date_timezone_names();
date_ampm();
============================================================================
Miscellaneous date manipulation functions
============================================================================
Pre-defined constants and functions that will handle pre-1970 and post-2038
dates in both PHP 4 and PHP 5, in any OS. Dates can be converted from one
type to another and date parts can be extracted from any date type.
DATE_DATETIME
DATE_ISO
DATE_UNIX
DATE_ARRAY
DATE_OBJECT
DATE_ICAL
date_convert()
date_is_valid();
date_part_is_valid();
date_part_extract();
============================================================================
Date calculation and navigation
============================================================================
date_difference() will find the time difference between any two days, measured
in seconds, minutes, hours, days, months, weeks, or years.
date_days_in_month();
date_days_in_year();
date_weeks_in_year();
date_last_day_of_month();
date_day_of_week();
date_day_of_week_name();
date_difference();
============================================================================
Date regex and format helpers
============================================================================
Pre-defined constants, an array of date format strings and their
equivalent regex strings.
DATE_REGEX_LOOSE is a very loose regex that will pull date parts out
of an ISO date with or without separators, using either 'T' or a space
to separate date and time, and with or without time.
date_format_date() is similar to format_date(), except it takes a
date object instead of a timestamp as the first parameter.
DATE_FORMAT_ISO
DATE_FORMAT_DATETIME
DATE_FORMAT_UNIX
DATE_FORMAT_ICAL
DATE_REGEX_ISO
DATE_REGEX_DATETIME
DATE_REGEX_LOOSE
date_format_date();
date_t()
date_short_formats();
date_medium_formats();
date_long_formats();
date_format_patterns();
============================================================================
Standardized ical parser and creator
============================================================================
The iCal parser is found in date_api_ical.inc, which is not included by default.
Include that file if you want to use these functions:
Complete rewrite of ical imports to parse vevents, vlocations, valarms,
and all kinds of timezone options and repeat rules for ical imports.
The function now sticks to parsing the ical into an array that can be used
in various ways. It no longer trys to convert timezones while parsing,
instead a date_ical_date_format() function is provided that can be used to
convert from the ical timezone to whatever timezone is desired in the
results. Repeat rules are parsed into an array which other modules can

============================================================================
Helpers for portable date SQL
============================================================================
The SQL functions are found in date_api_sql.inc, which is not included by default.
Include that file if you want to use these functions:
date_sql();
date_server_zone_adj();
date_sql_concat();
date_sql_pad();
============================================================================
Date forms and validators
============================================================================
Reusable, configurable, self-validating FAPI date elements are found in
date_api_elements.inc, which is not included by default. Include it
if you want to use these elements. To use them, create a form element
and set the '#type' to one of the following:
date_select
The date_select element will create a collection of form elements, with a
separate select or textfield for each date part. The whole collection will
get re-formatted back into a date value of the requested type during validation.
date_text
The date_text element will create a textfield that can contain a whole
date or any part of a date as text. The user input value will be re-formatted
back into a date value of the requested type during validation.
date_timezone
The date_timezone element will create a drop-down selector to pick a
timezone name.
The custom date elements require a few other pieces of information to work
correctly, like #date_format and #date_type. See the internal documentation
for more information.
============================================================================
Date Popup Module
============================================================================
A new module is included in the package that will enable a popup jQuery
calendar date picker and timepicker in date and time fields.
It is implemented as a custom form element, so set '#type' to 'date_popup'
to use this element. See the internal documentation for more information.
============================================================================
Date Repeat API
============================================================================
An API for repeating dates is available if installed. It can be used by
other modules to create a form element that will allow users to select
repeat rules and store those selections in an iCal RRULE string, and a
calculation function that will parse the RRULE and return an array of dates
that match those rules. The API is implemented in the Date module as a
new date widget if the Date Repeat API is installed.
============================================================================
Install file for dependent modules
============================================================================
The following code is an example of what should go in the .install file for
any module that uses the new Date API. This is needed to be sure the system
is not using an earlier version of the API that didn't include all these new
features. Testing for version '5.2' will pick up any version on or after the
change to the new API.
/**
* Implementation of hook_requirements().
*/
function calendar_requirements($phase) {
$requirements = array();
$t = get_t();
// This is the minimum required version for the Date API so that it will
work with this module.
$required_version = 5.2;
// Make sure the matching version of date_api is installed.
// Use info instead of an error at install time since the problem may
// just be that they were installed in the wrong order.
switch ($phase) {
case 'runtime':
if (variable_get('date_api_version', 0) < $required_version) {
$requirements['calendar_api_version'] = array(

*
* Fill the element #default_value with a date in datetime format,
* (YYYY-MM-DD HH:MM:SS), adjusted to the proper local timezone.
*
* NOTE - Converting a date stored in the database from UTC to the local zone
* and converting it back to UTC before storing it is not handled by this
* element and must be done in pre-form and post-form processing!!
*
* The date_select element will create a collection of form elements, with a
* separate select or textfield for each date part. The whole collection will
* get re-formatted back into a date value of the requested type during validation.
*
* The date_text element will create a textfield that can contain a whole
* date or any part of a date as text. The user input value will be re-formatted
* back into a date value of the requested type during validation.
*
* The date_timezone element will create a drop-down selector to pick a
* timezone name.
*
* #date_timezone
* The local timezone to be used to create this date.
*
* #date_format
* A format string that describes the format and order of date parts to
* display in the edit form for this element. This makes it possible
* to show date parts in a custom order, or to leave some of them out.
* Be sure to add 'A' or 'a' to get an am/pm selector. Defaults to the
* short site default format.
*
* #date_label_position
* Handling option for date part labels, like 'Year', 'Month', and 'Day',
* can be 'above' the date part, 'within' it, or 'none', default is 'above'.
* The 'within' option shows the label as the first option in a select list
* or the default value for an empty textfield, taking up less screen space.
*
* #date_increment
* Increment minutes and seconds by this amount, default is 1.
*
* #date_year_range
* The number of years to go back and forward in a year selector,
* default is -3:+3 (3 back and 3 forward).
*
* #date_text_parts
* Array of date parts that should use textfields instead of selects
* i.e. array('year') will format the year as a textfield and other
* date parts as drop-down selects.

* Code to add a date repeat selection form to a date field and create

*
* Moved to a separate file since it is not used on most pages

*
* Currently implemented:
* INTERVAL, UNTIL, EXDATE, RDATE, BYDAY, BYMONTHDAY, BYMONTH,
* YEARLY, MONTHLY, WEEKLY, DAILY
*
* Currently not implemented:
*
* BYYEARDAY, MINUTELY, HOURLY, SECONDLY, BYMINUTE, BYHOUR, BYSECOND
* These could be implemented in the future.
*
* COUNT
* The goal of this module is to create a way we can parse an iCal
* RRULE and pull out just dates for a specified date range, for
* instance with a date that repeats daily for several years, we might
* want to only be able to pull out the dates for the current year.
*
* Adding COUNT to the rules we create makes it impossible to do that
* without parsing and computing the whole range of dates that the rule
* will create. COUNT is left off of the user form completely for this
* reason.
*
* BYSETPOS
* Seldom used anywhere, so no reason to complicated the code.

<p>
Once the Date API is installed, all functions in the API are available to be used
anywhere by any module. If the Date Timezone module is installed, the system site
timezone selector and the user timezone selectors are overwritten to allow the
selection of timezone names instead of offsets. Proper timezone conversion
requires knowledge of those timezone names, something that is not currently
available in Drupal core, and the change in selectors makes it possible to track it.
</p>
<p>
In most cases, you should enable the Date Timezone module any time you use the
Date API to be able to set the site and user timezone names. It is not enabled by
default in case another module is setting timezone names in the database.
</p>
<p>
The API uses the PHP 5.2 date functions to create and manipulate dates, and
contains an option module that will emulate those functions in earlier versions
of PHP.
</p>
<p>
If you are using PHP 4 or PHP 5.0 or 5.1, native date handling won't work right.
Install the Date_PHP4 module to enable wrapper functions so this code will work
in old PHP versions.

<p>The generic date argument is based on ISO 8601 date duration and time interval standards, and allows you to create an flexible argument for any date range for any date field.
</p><p>The argument expects a value like 2006-01-01--2006-01-15, or 2006-W24, or @P1W. Separate from and to dates or date and period with a double hyphen (--)
</p><p>From and to dates in argument are ISO dates, but can be shortened and missing parts will be added. Omitted parts of ISO dates will be assumed to be the first possible (for the from date) or the last possible (for the to date) value in that time period.
</p><p>The 'to' portion of the argument can be eliminated if it is the same as the 'from' portion Use @ instead of a date to substitute in the current date and time.
</p><p>Shortcuts are available:
</p><p>Use periods (P1H, P1D, P1W, P1M, P1Y) to get next hour/day/week/month/year from now. Use date before P sign to get next hour/day/week/month/year from that date. The ISO standard calls for a separator (--) between a date and the P, but the separator is optional between a start date and a period in this argument to make the result easier to read.

The Date Copy module allows you to import date data into CCK nodes. Currently you can convert Event nodes to CCK nodes or import date data from an iCal feed.
<h3>Importing from Event Nodes</h3>
If you currently have date information in Event nodes and want to get the event dates into CCK Date fields instead, you can do this using the Date Copy module included with the Date module.
<ol>
<li>First, create the content type you want to import your events into and make sure the content type has a CCK date field and a field to hold the event description (either a body or a text field). You can create a new content type for this purpose or add a CCK date field to the current event type, depending on whether you want to create new nodes and nids or use the current ones.</li>
<li>Make sure you set up the CCK date field to have both a 'From Date' and a 'To Date'. If your events have event-specific timezones, make sure the CCK date field is set up to use the date's timezone.</li>
<li>Go to Admin >> Content management >> Date Import/Export >> Import >> Events and select 'Events' as the content type to import from and your new content type as the type to import to. Only content types that have date fields will appear in the list of available content types.</li>
<li>If you have added the new date fields to the current content type, be sure to select the option to NOT delete the old node after the import. If you have created a new content type, you will probably want to delete the old nodes.</li>
<li>You can select the number of items to import and the starting nid (import will be done in ascending nid order). Use that to import a single node as a test to be sure the results are what you want.</li>
<li>Once your nodes seem to be importing correctly, go ahead and import more of them. You may want to do them in batches to keep the server from timing out.</li>

<p>The DateTime object is defined in PHP versions 5.2 and greater. Full documentation can be found at <a href="http://php.net/datetime">php.net/datetime</a>.</p>
<p>PHP's <strong>print_r()</strong>, <a href="http://drupal.org/project/devel">Devel module</a>'s <strong>dpm()</strong>, and similar functions and most debuggers are not able to show the properties of DateTime objects. The <strong>date_format()</strong> function provides a good alternate method to debug DateTime objects. An example of its usage follows, including some common DateTime manipulation functions;</p>

<p>The date field can be displayed, or formatted, several ways, some configurable in the date settings, others that are automatically provided as options.</p>
<p>You'll see these formatters as options on the 'Display fields' screen and when you add the fields to Views. You can also use these formatters in custom code by doing something like:</p>
<pre>
print content_format('field_date', $node->field_date[0], 'iso');
</pre>
<h3>Formatter settings</h3>
<p>In many places you can further control the way multiple value dates will be displayed with formatter settings. The formatter settings look like:</p>
<div class="form-item" id="">
<select name="" class="form-select" id="" ><option value="default" selected="selected">Default</option><option value="format_interval">As Time Ago</option><option value="long">Long</option><option value="medium">Medium</option><option value="short">Short</option><option value="date">Date only</option><option value="time">Time only</option><option value="hidden">&lt;Hidden&gt;</option></select>
</div>
<div class="form-item" id="">
<select name="" class="form-select" id="" ><option value="both" selected="selected">Display From and To dates</option><option value="value">Display From date only</option><option value="value2">Display To date only</option></select>
</div>
<div class="form-item" id="">
<span class="field-prefix">Show </span> <input type="text" maxlength="128" name="" id="" size="5" value="5" class="form-text" /> <span class="field-suffix"> value(s)</span>
</div>
<div class="form-item" id="">
<span class="field-prefix">starting from </span> <input type="text" maxlength="128" name="" id="" size="15" value="now" class="form-text" /> <span class="field-suffix"></span>
</div>
<div class="form-item" id="">
<span class="field-prefix">ending on </span> <input type="text" maxlength="128" name="" id="" size="15" value="now +2 weeks" class="form-text" /> <span class="field-suffix"></span>
</div>
<div class="form-item" id="">
<select name="" class="form-select" id="" ><option value="show" selected="selected">Display repeat rule</option><option value="hide">Hide repeat rule</option></select>
</div>
<p>The number of values should be a numeric value, or blank to show all dates that match your other options.
'Starting from' and 'Ending on' can be a fixed dates in ISO format (like 2009-03-03T10:30:00) or relative times like 'now' or 'now +1 day'.
</p>
<h3>Formats and Format Types</h3>
<p>Formatter options include:</p>
<dl>
<dt>default</dt>
<dd>The main way to display this date, configured in the Date settings, defaults to the site short format.</dd>
<dt>short</dt>
<dd>The site short format.</dd>
<dt>medium</dt>
<dd>The site medium format.</dd>
<dt>long</dt>
<dd>The site long format.</dd>
<dt>time</dt>
<dd>Display the date time only, using the time format in the default display.</dd>
<dt>time_timezone</dt>
<dd>Display the date time and timezone, using the time format in the default display.</dd>
<dt>iso</dt>
<dd>Display the date in the standard ISO format of YYYY-MM-DDTHH:MM:SS.</dd>
<dt>ical</dt>
<dd>Display the date in the standard iCal format of YYYYMMDDTHHMMSS.</dd>
<dt>timestamp</dt>
<dd>Display the date as the Unix timestamp value.</dd>
<dt>format_interval</dt>
<dd>Display the date as 'XX days, XX hours ago' or 'XX months, XX days from now'.</dd>
</dl>
<p> To set up custom formats and formatters, go to <a href="&base_url&admin/settings/date-time/formats">admin/settings/date-time/formats</a>. You can either use a pre-configured display format, or create your own formatters and formats. Define a php date format string like 'm-d-Y H:i' (see <a href="http://php.net/date">http://php.net/date</a> for more details on custom format strings.)</p>

<p><strong>Note:</strong> The Date API is designed to use the new PHP date and timezone functions that are available in PHP 5.2 and above. If you're using an earlier version of PHP, you'll need to enable the Date PHP4 module which provides some wrapper code to emulate those functions. The wrapper code is slower and less efficient than the native date functions, so if at all possible, you will want to run on a server that uses PHP 5.2 or higher for the best performance. Some distros, like Red Hat, use PHP 5.1 instead. See <a href="http://bluhaloit.wordpress.com/2008/03/13/installing-php-52x-on-redhat-es5-centos-5-etc/">Installing PHP 5.2 on RedHat</a> for ideas on how to update that.</p>
<p>PHP 4 substitutions for the PHP 5 date functions are supplied if the Date PHP4 module is enabled. Use the PHP 5
functions in your code as they would normally be used and the PHP 4
alternatives will be automatically be substituted in when needed.
</p>
<p>
You cannot do everything with these functions that can be done in PHP 5, but
you can create dates, find timezone offsets, and format the results.
Timezone handling uses native PHP 5 functions when available and degrades
automatically for PHP 4 to use substitutions like those
provided in previous versions of the Date and Event modules.
</p>
<p>
Read the doxygen documentation in this module for more information
about using the functions in ways that will work in PHP 4.
</p>
<p>
The following functions are emulated in PHP4:
</p>
<ul style="color: rgb(0, 0, 187);">
<li>
date_create()
</li><li>
date_date_set()
</li><li>
date_format()
</li><li>
date_offset_get()
</li><li>
date_timezone_set()

<h2>Creating a timezone form item using Date API</h2>
<p>
This is simple. Just use the 'date_timezone' type, which is provided by date_api.module.
</p>
<pre>
&lt;?php
$form['timezone'] = array(
'#type' => 'date_timezone',
'#default_value' => $timezone,
'#description' => "Select a timezone if all the events will happen in the same place. Select that place's timezone",
);
?&gt;
</pre>
<h2>Converting to and from UTC</h2>
<p>
In the new system you just need to know the timezone name and either the UTC or local time. We store the UTC time and the timezone name in the database (in two separate fields). We retrieve that data and do:
</p>
<pre>
&lt;?php
$date = the UTC value from the database
$local_zone = the name of the local timezone
$type = the type of date value, DATE_DATETIME, DATE_ISO, or DATE_UNIX
$date = date_make_date($date, 'UTC', $type);
date_timezone_set($date, timezone_open($local_zone);
$date now contains the local value of the date.
Output it like:
print date_format_date($date, 'custom', 'm/d/Y H:i');
?&gt;
</pre>
<p>
To convert a local date back to UTC to store it in the database, do:
</p>
<pre>
&lt;?php
$date = local date value
$local_zone = the name of the local timezone
$type = the type of date value, DATE_DATETIME, DATE_ISO, or DATE_UNIX
$date = date_make_date($date, $local_zone, $type);
date_timezone_set($date, timezone_open('UTC');
$date now contains the UTC value of the date.
Output it like:
print date_format_date($date, 'custom', 'm/d/Y H:i');
?&gt;
</pre>
<h2>Use of timezone abbreviations</h2>
<p>
The API doesn't handle <a href="http://www.timeanddate.com/library/abbreviations/timezones/">timezone abbreviations</a> at all, there's no way to do it right because they are not unique (EST could be Eastern Standard Time or European Summer Time). We need the full, undeprecated timezone name, which looks like 'America/Chicago'. It is comprised of the name of the continent and the major city in the timezone. Older names like 'US/Central' are deprecated because the area names change, but city names rarely do. Some good info about timezones is at http://en.wikipedia.org/wiki/Zoneinfo.
</p><p>
Also, we do not use spaces in the timezone names, so we use America/New_York, not America/New York. The PHP 5.2 date functions and MYSQL native timezone handling all expect names without spaces in them to work correctly.
</p><p>
You can use the <a href="http://php.net/manual/en/function.timezone-name-from-abbr.php">php function <code>timezone_name_from_abbr()</code></a> to try to translate to and from abbreviations, but it's not entirely reliable, as noted above. If we have the current offset and we know if it's currently daylight savings time or not, you can combine that with the abbreviation to get the timezone name, but that's a lot of 'if's.
</p>
<h2>Timezone Names</h2>
<p>
The complete list of allowed, undeprecated timezone names is:

<h3>Date Fields</h3>
<p>The CCK Date field uses the <a href="topic:date_api/overview">Date API</a> to create date fields and widgets.</p>
<p>You have a choice of creating an ISO date or a unix timestamp. If you are porting information from another application you may want to create a field using a type that matches the source data. Some advantages and disadvantages of each include:</p>
<dl>
<dt>Datestamp (Unix Timestamp)</dt>
<dd><ul>
<li>Stores the date as an integer.</li>
<li>Takes up less room in the database because it's smaller.</li>
<li>Often easier to use for date calculations because you can increase or decrease it just by adding or subtracting seconds.</li>
<li>It is the format used by php date functions.</li>
<li>It must be filled with a complete date -- year, month, day, hour, minute, second, so you sometimes have to arbitrarily set some of these values even if they are not applicable.</li>
</ul></dd>
<dt>Date (ISO Date)</dt>
<dd><ul>
<li>Stores the date in an ISO format (YYYY-MM-DDTHH:MM:SS).</li>
<li>The data is in a human-readable form.</li>
<li>You can use it for incomplete dates, i.e. only a year or only a year and a month, and pad the other values with zeros, so it does not appear to be any more precise than it really is.</li>
<li>It is a format that is internationally-recognized, and it is used as-is on many web sites and in many applications.</li>
</ul></dd>
<dt>Datetime</dt>
<dd><ul>
<li>Stores the date in the database's native date format (YYYY-MM-DD HH:MM:SS).</li>
<li>The data is in a human-readable form.</li>
<li>You can use it for incomplete dates, i.e. only a year or only a year and a month, and pad the other values with zeros, so it does not appear to be any more precise than it really is.</li>
<li>It can take advantage of the database's date handling functions without any conversion.</li>
</ul></dd>
</dl>
<h3>Date Widgets</h3>
<p>There are several widgets to choose from to control how users can enter data for this field.</p>
<dl>
<dt>Text Field</dt><dd>The Text Field date widget uses a custom format set in the field settings, like '31.12.2008'. As a fallback the widget will try to accept input allowed by the php <a href="http://www.php.net/manual/en/function.strtotime.php">strtotime function</a>. This allows the user to type a date in in many natural formats, like 'March 31, 1980'.
There are limitations to strtotime, so setting a custom format is more reliable. The strtotime function will assume date shortcuts are in American format (MM/DD/YY), and strtotime will not work for dates prior to 1970.
</dd>
<dt>Select List</dt><dd>The Select List date widget presents users with a drop-down list or textfield for each part of the date (year, month, day, hour, etc.). The whole selector is collapsed onto a single line using css (except for the timezone selector, if date-specific timezones are collected). The selector is highly configurable and you can set it up to use 5, 10, or 15 minute increments for minutes and seconds, or make some parts of the selector use textfields instead of drop-downs, useful to allow any year without creating a huge drop-down selector.</dd>
<dt>jQuery Pop-up Calendar</dt><dd>The Javascript Pop-up Calendar is offered as an input alternative if the Date Popup module is installed. The date is split into date and time fields, and the date field uses a jQuery popup calendar and the time field uses a jQuery timeselector widget that only allows valid time input.
</dl>
<p>If you have the Date Repeat module enabled, you will also see options for each of those widgets that include a repeat options selection form that will allow the user to choose values like 'Every week' or 'The last Tuesday'.</p>

<h3>Embedding Views</h3>
<p>Embed a date browser view anywhere using the format:</p>
<pre>date_embed_view($view_name, $display_name, $settings, $args)</pre>
<p>Settings are used to override some values of the view.</p>
<p>The primary setting that is useful here is a setting for 'block_identifier'. The view's block_identifier is used to control individual instances of regular and embedded views that contain date navigation so that they move separately or together. All views that use the same identifier will move together.
All views that use different identifiers will move independently. The identifier will show up in the url as a querystring, like node/275?mini=calendar/2008-10.
</p>
<h3>Examples:</h3>
<dl>
<dt>&lt;?php print date_embed_view('myview', 'page_1'); ?&gt;</dt>
<dd>This will embed the first page display in the view 'myview'.</dd>
<dt>&lt;?php print date_embed_view('myview', 'page_1', array('block_identifer' => 'embedded'), array('2008-W45')); ?&gt;</dt>
<dd>This will embed the first page display of the view and use 'embedded' as an identifier, set to show the week view for week 45 of 2008.</dd>
<dt>&lt;?php print date_embed_view('myview', 'block_1', array('block_identifier' => 'mini'), array('2008-07')); ?&gt;</dt>
<dd>This will embed the first block view of the view and use 'mini' as an identifier, set to show the month view for July 2008.</dd>

<h3>Usage example of date elements within forms</h3>
<p>
* Enable the Date API module (you might want to add a dependency in the .info file of your module).
* Date API uses <a href="http://api.drupal.org/api/function/hook_elements">hook_elements()</a> to create custom form types. You can check the file date_api_elements.inc for the list of form types available, and for other configuration options.
</p>
<p>
Adding a date form element is then easy.
<pre>
&lt;?php
/**
* Your form builder.
*/
function mymodule_form($form_state) {
$form = array();
// [...snip...] add many fields to your form
// Creating the date/time element starts here
// Provide a default date in the format YYYY-MM-DD HH:MM:SS.
$date = '2008-12-31 00:00:00';
// Provide a format using regular PHP format parts (see documentation on php.net).
// If you're using a date_select, the format will control the order of the date parts in the selector,
// rearrange them any way you like. Parts left out of the format will not be displayed to the user.
$format = 'Y-m-d H:i';
$form['date2'] = array(
'#type' => 'date_select', // types 'date_text' and 'date_timezone' are also supported. See .inc file.
'#title' => 'select a date',
'#default_value' => $date,
'#date_format' => $format,
'#date_label_position' => 'within', // See other available attributes and what they do in date_api_elements.inc
'#date_timezone' => 'America/Chicago', // Optional, if your date has a timezone other than the site timezone.
'#date_increment' => 15, // Optional, used by the date_select and date_popup elements to increment minutes and seconds.
'#date_year_range' => '-3:+3', // Optional, used to set the year range (back 3 years and forward 3 years is the default).
);
// [...snip...] more fields, including the 'submit' button.
return $form;
}
?&gt;
</pre>
<p>These are self-validating elements, you shouldn't need to do anything except include them in your form. You pass them parameters for the timezone, format, and a default value in the format YYYY-MM-DD HH:MM:SS, and it will convert your input into the format the element wants, split the date and time into different fields as needed, then accept and validate the user input and convert it back into a string in the same format you originally provided (YYYY-MM-DD HH:MM:SS). So you pass it a string and it will pass back a string by the time you get to your own validation function.
</p><p>
You are responsible for doing your own timezone conversion, the element uses the timezone just so it can create a date object with the right timezone for doing its formatting. So if you need to do timezone conversion, you pull your UTC date out of the database and convert it to a local date, pass that value to the Date element, then take what it returns and convert it back to UTC and store it in the database again.
</p><p>
If the Date Popup module is enabled, a date_popup element can be used. It works like the other elements, but splits the date and time into separate parts. You control whether it uses date or date and time by the format you supply in #date_format. If you don't have any time parts in the format, you won't get a time element. Note that the jquery widget (the 'date' part of the popup) can only accept a limited number of formats, things like Y-m-d or m/d/Y or d.m.Y.

<ul>
<li>The Date API now uses PHP 5.2 date functions for better date and timezone handling (and has PHP 4 emulations for those functions so the module will work in PHP4). Although the code will work with PHP 4, it is <strong>significantly</strong> faster and more efficient under PHP 5.2 or higher, so PHP 5.2 is highly recommended.</li>
<li>The database query handling has been completely re-worked to take advantage of database timezone handling when available, with a fallback to the older and less reliable method of using offsets to do timezone adjustments.</li>
<li>No more need for the adodb date library, historical dates earlier than 1970 and later than 2038 are handled without any external code.</li>
<li> iCal integration is greatly improved, an iCal parser can parse events, alarms, most types of dates and timezones, duration, repeat rules, and more.</lI>
<li>The Date API creates date elements that can be used by any module, including 'date_select', 'date_textfield', and 'date_timezone'.</li>
<li> A new Date Timezone module overrides the site and user timezone selectors to allow you to select a timezone name instead of a timezone offset, and that stored name is used to properly adjust date values. It also detects the user's timezone name automatically and updates the user record with that name.</li>
<li>A new Date Popup module creates a jQuery popup calendar date picker and time picker, and the element is available to other modules as a form type of 'date_popup'. </li>
<li>The Date module now has lots of new ways to define default values -- you can set a the default to 'blank', 'now', or 'relative', where relative is something like '+90 days'. The To date has a separate default value, which can be the same as the From date or do something different.</li>
<li>A Date Repeat API module has been added which can be used by any other module. The CCK Date module uses it to allow you to select 'repeating' as a type of multiple date, present the user with a form to select the repeat rules for their date, and then create all the multiple values that match those rules.</li>
