Kopi Vs Sunbird: Summertime-related Problem, 1hr time shift when viewing kopi ics Options

[tml]

Hi,

Since the switch to summertime here in Europe (CET, GMT+1), I experience some slight incompatibilities between Mozilla Sunbird (Win XP) & Ko/pi (@Zaurus SL C3100).

I usually load korganizer.ics in Sunbird as remote/read-only calender. This worked fine all winter long, but now entries from korganizer.ics are displayed 1hr too late in sunbird -- which ... well, made me already miss one meeting.

The timezone setting in ko/pi@zaurus is CET + Summertime. The timezone setting in sunbird@WinXP is Europe/Vienna (no option to set summertime here, so I assume this is done automatically).

When I synchronize korganizer.ics with another file the time settings in the sync'ed file seem correct though. (But synchronizing is no viable solution in this case.)

So, does somebody else experience similar problems? Does somebody have any advice? I tried to solve this problem for several weeks now (well, since the switch to summer time). The only solution I have been able to come up with yet is to wait until autumn -- which is not a viable option, I'd say

Any advice?

Thanks,
Thomas.

What about simply not changing to the "summer" setting?

Well, MS Windows switches to summer-time, which is when the trouble started. I now set summertime, loaded a backup, saved the calendar (as described in the help), and it looks good so far. But I had it looking that good already before once for a few days, but then the problem re-occurred, which is the reason why I'm somewhat puzzled. We'll see if it works this time.

Another incompatibility comes to light with repeated events that begin before summer-time comes into effect and ends afterwards. Sunbird displays the events before the switch correctly but then displays dates after the switch with a +1 hr time shift. I'm not sure which one does it right, though.

I think the problem lies here. While kopi make timestamps like this (without explicit time zone, saving times as GMT)

CODE

DTSTART:20070301T160000Z
DTEND:20070301T200000Z

Sunbird adds timezone info & saves dates with local time stamps:

CODE

DTSTART;TZID=/mozilla.org/20070129_1/Europe/Vienna:20070316T100000
DTEND;TZID=/mozilla.org/20070129_1/Europe/Vienna:20070316T110000

So the question probably is if there is a way to make kopi add time zone information?
