Hi,

after a good deal of thought we did some server migrations
and have also re-installed the open-xchange server on the
new hardware. So far so good everything seems to be working
again, but not the appointments.

Whenever I create an new appointment in outlook it moves 1 hour
into the past after is has synchronized with open xchange.
If I take a look into the web-calender the appointment was 
created with the specified time.

So there's always a time difference between OX and Outlook:
Outlook-Time = (OX-Time - 1 hour)

I've also checked the system timezone. Everything's the same
like on the old ox server.
..."date" tells me: <Date> CEST 2006
 -> Date is the same like on my windows clients

..."tzconfig" tells me: Europe/Vienna

Also the ldap settings are the same. So I'm pretty clueless
what else I can do. Furthermore I don't know much about how to
configure/set locales/timezones.

Maybe there's some kind of GMT setting, that should be changed?
I only know that my clients do have GMT+1 (Vienna) set and that
tzdata (Time zone and Daylight Saving Time Data) is installed on
my debian system.

clemens
