Give a proper example that can be reproduced. Specify your timezone.

have the same situation

software:

Debian 6.0.6 x64

libsope-appserver4.9 -- 4.9.r1664.20121206
libsope-core4.9 -- 4.9.r1664.20121206
libsope-gdl1-4.9 -- 4.9.r1664.20121206
libsope-ldap4.9 -- 4.9.r1664.20121206
libsope-mime4.9 -- 4.9.r1664.20121206
libsope-xml4.9 -- 4.9.r1664.20121206
sope4.9-libxmlsaxdriver -- 4.9.r1664.20121206
sogo -- 2.0.3a-1

time settings:
# date
Tue Jan 15 13:10:50 MSK 2013
# cat /etc/timezone
Europe/Moscow
# cat /home/sogo/GNUstep/Defaults/.GNUstepDefaults | grep -i timezone
SOGoTimeZone = Europe/Moscow;

and when I create an event from 17.00 till 18.00, I have event source like this:

BEGIN:VEVENT
UID:3B61-50F51C80-7-63928580
SUMMARY:New Event
CLASS:PUBLIC
CREATED:20130115T090902Z

DTEND;TZID=Europe/Moscow:20130115T163000
TRANSP:OPAQUE
END:VEVENT
END:VCALENDAR

you can see time shift - 1:30

and what else is very strange for me, I have double time zone records in web-interface Preferences

already compiled sogo 2.0.3a, sogo 2.0.2a and sope from source - nothing changed

zymanch, unless you toyed around with the event, it's wrong because it has no VTIMEZONE definitions.

gray_graff your event is also wrong as you should have 2 VTIMEZONE definitions (STANDARD and DAYLIGHT). Moreover, you should have plenty of RDATE entries too.

So you must have messed up with the timezone files included in SOGo.

The problem is that SOGo doesn't handle RDATES (see iCalTimeZonePeriod.m).

For the moment, I rolled back (and updated) the timezones definitions to a more compatible format (with no RDATE). This is the format used by Thunderbird/Lightning.

See https://github.com/inverse-inc/sogo/commit/9ac8e9f0e116d4630b1637f2938d541e0e23e796 [^]

francis, excuse me for the stupid question, but where I can find files for editing?
I already changed time-zone file in /usr/lib/GNUstep/Libraries/Resources/NGCards/TimeZones/Europe, but after sogo server, apache & memcached restart noting changes - event source stay the same like before editing.
