problems with changed timezone

[demchenko]

Hi,
Not a while ago, goverment cancelled daylight saving time in Russia, so every russian zone changed, for example Europe/Moscow now is GMT+4 MSK, not GMT+3/+4 MSK/MSD.
As last update for zimbra opensource didnt contains update for timezones, I tried to change them manually: edited zimbra/conf/timezone.ics so Moscow timezone looks like this:

BEGIN:VTIMEZONE
TZID:Europe/Moscow
LAST-MODIFIED:20111109T120700Z
X-ZIMBRA-TZ-PRIMARY:TRUE
X-ZIMBRA-TZ-MATCH-SCORE:100
X-ZIMBRA-TZ-ALIAS:(GMT+04.00) Moscow / St. Petersburg / Volgograd
X-ZIMBRA-TZ-ALIAS:(UTC+04.00) Moscow / St. Petersburg / Volgograd
BEGIN:STANDARD
TZNAME:MSK
DTSTART:19710101T020000
TZOFFSETTO:+0400
TZOFFSETFROM:+0400
END:STANDARD
END:VTIMEZONE

then restarted mailboxd.

Well, as i can tell it works fine - time in appointments is set correctly. However, description in web interface (in admin or personal settings, in COS settins, in domain settings) still labels this zone as "(GMT+03) Moscow St.Petersburg Volgograd", same phrase is put in invitations cards:

Description:
	

The following is a new meeting request: Subject: test4 Organizer: "Демченко Юрий Александрович" <y.demchenko@csbigroup.ru> Time: Friday, November 11, 2011, 12:00:00 PM - 12:30:00 PM GMT +03:00 Moscow, St. Petersburg, Volgograd Invitees: demchenko.ya@gmail.com

And while in web-interface, calendar shows meetings in right cells (for example, i set up meeting from noon to 13:00 - it shows in cells from noon to 13:00), but when i move up cursor above it - popup shows wrong time (from 13:00 to 14:00).

So, my question is - how do i fix this? I need Moscow timezone to be GMT+4 without errors.

Another problem - I set preferences for default COS - timezone "Europe/Moscow", same in preferences for my domain, same in personal account preferences, but still for new meetings i get wrong timezone set by default - GMT+4 Tbilisi (before i changed timezone.ics, i tried just to change default COS settings and set this timezone as default). How do i fix this?

am I only one who uses ZCS in Russia? noone else had that problem?

[aviriel]

Agree with the question. Can we wait in 7.1.4 the patch with fixing a problem with changing the time zone for russian users?

I have this problem too. I also as you changed timezones.ics, but problem not resolved. I also converted existing appointments according this guide Changing ZCS Time Zones - Zimbra :: Wiki May be we should submit a bug report? I'm not sure that zimbra guys know about cancelling daylight saving time in Russia.
