TIMEZONE Problems

[Christoph_Kaulich_GN]

Hello,

I am using egw 14, and found some interesting things in the CALDAV
output.

I have a regular meeting with some exceptions and got the following
block in the ics file:

BEGIN:VEVENT
EXDATE;TZID=Europe/Berlin:20160121T080000Z,20160122T080000Z,20160222T080000

Z,20160301T080000Z,20160302T080000Z,20160303T080000Z,20160307T080000Z,20160

317T080000Z,20160324T080000Z,20160330T070000Z,20160412T070000Z,20160413T070
000Z,20160414T070000Z
X-MOZ-GENERATION:2
SUMMARY:Standup

which for my understanding mixes in the EXDATE block different
timezones, in the beginning it states Europe/Berlin, and than it adds
the Z for the UTC timezone. This makes for example emClient not working
correct.

Is this a client or a server problem?

Thanks

Christoph

It’s a problem caused on our side together with Horde_Icalendar class,
which only exports EXDATE in Zulu-time (UTC), even if a timezone given.
For other attributes like RECURRENCE-ID it decides depending on timezone
given or not.

I removed timezone for now and will get in touch with Horde, why EXDATE
does not allow a timezone, like eg. Apple Calendar on OS X does it for
EXDATE and RECURRENCE-ID.
