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.

Nightly update for 6.1 branch of the Date module.

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.

Version 1.7
===========

- Move cached views info to cache_views so it gets cleared when views_invalidate_cache() is called.

Version 1.5
===========

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.

stored in date object or displayed;
