Summary0001472: SOGo uses wront DST end date for Europe/Vienna (last sunday of september rather than of october)
Description

I'm using KOrganizer with the CalDAV ressource to create events in SOGo. Both, KOrganizer and SOGo have Europe/Vienna configured as their time zone. However, all dates in October will be shifted one hour later in the web UI. For a sample event see the attached files (downloaded via webdav from the calendar's webdav directory, so they are really what the SOGo server uses). My guess is that SOGo takes the first
BEGIN:STANDARD
...
END:STANDARD
block in the VTIMEZONE to calculate the end date for daylight saving time (the first such block specifies that in 1981-1995 the DST ended on the last sunday in september), even though the RRULE has a COUNT=15 and thus ended in 1995...

This also affects all recurring events: They are also shown one hour too late during october in Europe/Vienna.
I'll also attach a Screenshot.

TagsNo tags attached.
