Description Christoph Bartoschek 2009-06-02 12:47:56 UTC

Version:            (using Devel)
Installed from:    Compiled sources

korganizer seems to not honour different between different timezones for specific periods. For example the difference between the New York timezone and Berline timezone is normally 6 hours. But the daylight saving time starts earlier in the USA and ends later. This results in an offset of 5 hours in March and November. Korganizer seems to not honour that:

1. The local timezone is Berlin.
2. Create a new event on 2009-06-02. Let it start at 8:00 New York time
3. Let the event repeat each tuesday at the same time.
4. Korganizer correctly shows that the event takes place at 14:00 local time.
5. Go to March 2010. 
6. The event is still at 14:00 each tuesday in march although it should take place at 13:00 on some tuesdays.

I can confirm this bug - recurring meetings that have been setup in a different time zone then mine do not change time in my calendar, even if the offset between the two timezone changes (UK time and Pacific Time in this case).

KOrganizer version 4.4.5

Make recurring events aware of daylight saving time.

The time of the first occurrence was being used for all occurrences,
which is wrong. For example, a recurring UTC event that crosses a
DST switch won't have all occurrences with at same local time.
