date 5.x-2.x-dev

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.
* 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 is 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.
