The nightly snapshot for the 6.2 version (supersedes the 6.1 version).

Moving code to the 6.2 branch to coincide with the 5.2 version of Date and Views 2, and tagging an new alpha release that matches the just issued alpha release for the Calendar module.

Initial beta release with D6 compatibility.

Nightly update for 6.1 branch of the Date module.

NOTE! The new version has several new files and is completely re-organized. Empty the module folder completely before adding the contents of the new version. If you don't do that, Drupal may try to use some of the invalid, older files and things will not work correctly. After updating the files on your system, visit the modules page and look for the new Date/Time section and enable the new modules. Then visit update.php to update your database and make sure your site timezone name is correctly set at admin/settings/date-time.

If you use the Token module, be sure to use the latest version of it, too, currently that is the development version. The older version was using the older Date API.

This version should be matched up with the 5.2 version of the Calendar module.

* 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 significantly faster and more efficient under PHP 5.2 or higher, so PHP 5.2 is highly recommended.
* No more need for the adodb date library, historical dates earlier than 1970 and later than 2038 are handled without any external code.
* iCal integration is greatly improved, an iCal parser can parse events, alarms, most types of dates and timezones, duration, repeat rules, and more.
* The Date API creates date elements that can be used by any module, including 'date_select', 'date_textfield', and 'date_timezone'.
* A new Date Timezone module overloads 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.
* 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'.
* 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.
* 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.

This is a completely new version of the Date API, with lots of improvements and new features:

* 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).
* iCal integration is greatly improved, an iCal parser can parse events, alarms, most types of dates and timezones, duration, repeat rules, and more.
* The Date API creates date elements that can be used by any module, including 'date_select', 'date_textfield', and 'date_timezone'.
* A new Date Timezone module overloads 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.

Version 1.7

- 170371 make sure date api is available during updates.
- 163712 fix some subtle problems in link titles and query parameters when working with partial ISO dates, like only year and month.
- 175914 make sure month and day don't get set to zero when creating timestamps to format dates, since zero values will revert to the previous day.

- 156171 Timezone offsets were not getting saved. Fix that and repair the database.
- Make sure Views is enabled before including the file.
- Preparing for Version 5.2. The only database changes in 5.2 are changes to settings, so adding the enough changes to current version so it is possible to try 5.2 out and return to this version with no loss of data. In 5.2 settings changes will add several ways to control default values and other improvements which are just placekeepers to prevent data loss in this version.

Version 1.4
===========

NOTE Date API has been split out into a separate module to make the API available with no dependency on CCK. For best update results, uninstall the Date module before adding the updated file to the site, then immediately go to the modules page and enable both the Date and Date API modules.

- 126551 themeing improvements: 1) A 'timestamp' formatter which will return the timestamp value of a date. You can use that instead of a
formatter that returns a formatted value if you want to do your own formatting of the results. 2) A 'Days ago' formatter that applies
format_interval() to the date. It uses a theme_date_format_interval() to allow you to tailor the results depending on whether it is a future
or past date and incorporate both the To date and From date into the results. 3) All formatters now run through a theme to give you more
places to jump in and make changes to the display. The theme has the complete date object to work with. 4) A date_field_object() function
that will bring back a complete date object for a given field. The function description contains details about what exactly is in that
object, but it includes both from and to dates as timestamps, ISO dates and arrays of date parts.

- 123886 make sure cached data isn't empty
- 125803 get help text to display in selector widget
- 123365 fix Views filter to properly handle both from and to dates
- 121544 use 'From date' and 'To date' instead of 'From' and 'To' for better translations.
- 121259 split date api out so it can be used by other modules with no dependency on CCK
- 117791 add validation to submitted filter values to avoid creating invalid SQL
- Improve ISO week range function and add function to find last day of month
- 125483 more corrections to week calculation
- 125338 fix postgresql handling, lots of help from havran
- 124320 fix fatal errors in identifying include paths
- 123179 send date and node objects to theme to add more flexibility to ways that it can be displayed.
- 121259 fix to make transition to separate Date API easier since non-existant functions will cause fatal error that prevents ability to get
back to module installation page.
