That's a known bug in iCal as the standard doesn't enforce any order.

There are however SOGo Bugs for this.
See Bug #1118
http://www.sogo.nu/bugs/view.php?id=1118
And Bug #1203
http://www.sogo.nu/bugs/view.php?id=1203

[SOGo] Apple iCal vs. daylight time vs. RRULE

2012-03-28 Thread Thomas Paduch
Hi there,

since last weekend (switch to daylight time) there is an strange behavior
with Apple iCal (4.0.4 / Snow Leopard) and Events created via Web GUI.
All Events appears 1 hour later in Apple iCal. Events created with iCal 
or Thunderbird+Lightning displayed still correctly in Apple iCal. Also 
Thunderbird+Lightning and the Web GUI display all events correctly, only
iCal make something wrong.
The Timezone Support in Apple iCal is disabled.

If i change the RRULE in the STANDARD TIMEZONE Part of the event from:

RRULE:BYDAY=-1SU;FREQ=YEARLY;BYMONTH=10 

to

RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=10 

the Event in Apple iCal will be displayed correctly. At this moment we  

use an apache substitute (in the caldav vhost) as workaround:

  AddOutputFilterByType SUBSTITUTE text/html text/xml text/calendar
  Substitute 
's|RRULE:BYDAY=-1SU;FREQ=YEARLY;BYMONTH=10|RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=10|n'

... maybe it make sense to change the RRULE order for events created by
the Web GUI.

Best Regards,
  Thomas
