Hi,

Here is what's going on:
My server is located at (GMT-0300) Brasilia. Time and Timezone are correct in the server.

Code:
root$ date
Tue Nov  3 00:31:58 BRST 2009
I also have the following default configuration on Zimbra
Code:
zimbra@server:~$ zmprov gc default |grep -i timezone
zimbraPrefTimeZoneId: (GMT-03.00) Brasilia
zimbraPrefUseTimeZoneListInCalendar: TRUE
on my user I have the following settings:
Code:
zimbra@server:~$ zmprov ga USER |grep -i timezone
zimbraPrefTimeZoneId: (GMT-03.00) Brasilia
zimbraPrefUseTimeZoneListInCalendar: TRUE
However, when I create a new appointment, Zimbra automatically set the timezone to (GMT-0300) Argentina.

The main difference between Brasilia V.s. Argentina timezone is that Argentina doesn't have Daylight Saving. So, during this part of the year (end of October to end February) all appoints differ 1 hour.

Now my question is "From where is Zimbra bring up the ARGENTINA timezone?" is there a place that I can change it?

PS: I have Outlook Synchronization and when a create an appointment directly on Outlook (by forcing the timezone to Brasilia, manually) the appointment shows on Zimbra as Argentina Timezone. Any clue?

Fabio.
