|

* Recurrence rule iterator
|

*
|
|
* The constructor accepts times only as DateTime (or decendents like egw_date) to work timezone-correct.
|
|
* The timezone of the event is determined by timezone of the startime, other times get converted to that timezone.
|
|
*
|
|
* There's a static factory method calendar_rrule::event2rrule(array $event,$usertime=true), which converts an
|
|
* event read by calendar_bo::read() or calendar_bo::search() to a rrule iterator.
|
|
*
|
|
* The rrule iterator object can be casted to string, to get a human readable description of the rrule.
|
|
*
|
|
* There's an interactive test-form, if the class get's called directly: http://localhost/egroupware/calendar/inc/class.calendar_rrule.inc.php
|
|
*
|
|
* @todo Integrate iCal import and export, so all recurrence code resides just in this class
|
|
* @todo Implement COUNT, can be stored in enddate assuming counts are far smaller then timestamps (eg. < 1000 is a count)
|
|
* @todo Implement WKST (week start day), currently WKST=SU is used (this is not stored in current DB schema, it's a user preference)
