Kronolith web interface, KDE Kontact, Funambol+Outlook, and my Nokia Symbian S60 SyncML client do not exhibit this behaviour, so we have ruled out the Kronolith WebDAV server being the problem. Reproducible: Always Steps to Reproduce: 1. Book a weekly recurring event at 14:00 on January 1st, 2009 on a remote WebDAV calendar 2. Subscribe to calendar with Mozilla Lightning/Sunbird 3. Move view to May 2009 Alternately 1. Subscribe to remote calendar in Lightning/Sunbird 2. Book a weekly recurring event at 14:00 on January 1st, 2009 on a remote WebDAV calendar 3. Move view to May 2009 4. Reload remote calendars Actual Results: Event recurs at 15:00. Expected Results: Event should remain at 14:00. The problem also appears to occur on local calendars.
I just tested with internal storage, no problem. I assume your event gets stored in UTC, could you export your recurring event. Mine is as follows: BEGIN:VEVENT CREATED:20090522T062045Z LAST-MODIFIED:20090522T062102Z DTSTAMP:20090522T062102Z UID:dcf1d3c7-20dd-453f-bcb7-ef79bb097cc9 SUMMARY:weekly 1400 RRULE:FREQ=WEEKLY DTSTART;TZID=Europe/Amsterdam:20090204T140000 DTEND;TZID=Europe/Amsterdam:20090204T150000 END:VEVENT
Yes, it gets stored in UTC I believe. After following my steps to reproduce above, this is the exported event: BEGIN:VEVENT CREATED:20090522T143138Z LAST-MODIFIED:20090522T143138Z DTSTAMP:20090522T143138Z UID:0f0c0e5c-a79e-4792-bbbd-daf1fcd5b4c3 SUMMARY:Recurring Event UTC Bug STATUS:CONFIRMED CLASS:PUBLIC RECURRENCE-ID:20090603T190000Z DTSTART:20090603T190000Z DTEND:20090603T200000Z TRANSP:OPAQUE END:VEVENT
Can anybody else confirm the issue?
I don't see an error (but I have stated the same opinion in other bugs about the same issue, e.g. Bug 357383). - the time is fixed at 14:00 UTC - during standard time the UTC offset is +1 (timezone Europe/Berlin) - during daylight saving time the UTC offset is +2 (timezone Europe/Berlin) -> event will be displayed at 15:00 during winter and at 16:00 during summer I assume that your system uses a timezone that has standard and daylight saving time with different UTC offsets too.
I see, thanks for the link to the previous bug report. You are correct; my system is Ubuntu, with a UTC hardware clock and the local timezone in Linux set to America/New_York. I will mark this as a duplicate and make comments in the Bug 357383.
