Description Martin van Es 2006-11-15 17:36:44 UTC 
Version:           3.5.5 (using KDE 3.5.5, Kubuntu (edgy) 4:3.5.5-0ubuntu3)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-10-generic

I've stumbled accross a tzone problem in korganiser in combination with Zimbra

1. In an empty calendar, I create 1 single appointment from 10.00 to 11.00 (am)
2. I open this calendar in Korganiser and the appointment displays right(!)

The calendar file is now:

3. I change (location of) the item in Korganiser and save
4. When I reload, the item is moved back exactly 1 hour (09.00 - 10.00) in Korganiser, Zimbra still displays is at the right time, showing the new location.

The Calendar file is now this:

5. Whenever I move the item in konqueror (and save and reload) it will always be displayed one hour early.

this is what the Calendar file looks like after moving the appointment 1 hour forward in konqueror (to 10.00 - 11.00) after which it is again displayed an hour early (09.00 - 10.00).

I have no idea who is violating the vCal standards, I just know that during all the moving around of the appointment Zimbra kept displaying it at the original and right time.

I have a similar problem.

From Zimbra I recieve a ics with more than one VTIMEZONE:

BEGIN:VCALENDAR
PRODID:Zimbra-Calendar-Provider

METHOD:REQUEST
BEGIN:VTIMEZONE
TZID:(GMT-08.00) Pacific Time (US & Canada) / Tijuana

DTEND;TZID="(GMT+01.00) Amsterdam / Berlin / Bern / Rome / Stockholm / Vienn

Korganizer schedules the meeting at 18-19, corresponding to the first timezone (US-pacific), although the DTSTART refers to the other timezone.

If I remove the top timezone declaration it imports right.
If I switch the to declarations it also work.

Perhaps libkcal only uses the first VTIMEZONE and ignores TZID ?
Comment 2 Sergio Martins 2013-06-15 23:51:18 UTC 
tzid support was fixed in kde4.
