recurring event at noon UTC, wrongly displayed at 13:00 CEST during summer time
As a further complication, if I then dissociate an instance of that recurring event during summer time, the dissociated event will suddenly shift to the correct 14:00 CEST! This is very confusing, unless you know that the recurring event was displayed at the wrong time. A normal user will not understand this. Hmm... It seems to be also related to this problem: I use KDE 3.5.10 and sync with Google Calendar via GCALDaemon through *.ics file. During the winter all seemed to be synchronized correctly. But now after a switch to summer time I see the following: all recurring events start one hour later and all single events have correct time. I guess time for recurring events is somehow distorted in *.ics files produced by KOrganizer (new and old). The problem seems to be, that KDE3 calendar files and the attached file 'UTC_Summertime.ics' only contain time for all events in UTC format and no information about timezone or DST. If KOrganizer opens this kind of file, it doesn't ask you, whether you want to choose absolute or relative time. No dialog popping up. Changing timezone in KOrganizer may act as a workaround: Settings -> Configure KOrganizer -> Time and Date. Then a dialog window "Keep Absolute Times?" WILL pop-up: "The time zone setting was changed. Do you want to keep the absolute time of the items in your calendar, which will show them to be at a different time than before, or move them to be at the old time also in the new time zone?" So if you want time to remain in UTC, choose "Keep Times". Version: Using KDE 4.4.1 OS: Linux Installed from: Kubuntu packages (from riddell's PPA for Karmic) I added a one-off event for Wednesday, 7 April 2010 for 16:30 UTC. It should have appeared at 17:30 BST in my calendar. Instead it was placed as 15:30 BST. This issue appears to be resolved in KDE 4.4.2. Tested using Kontact under 4.4.2 on Kubuntu (riddell's ppa). This problem seems to have reappeared in 4.7. I am not sure whether these are related, but it sounds similar to what I reported recently in https://bugs.kde.org/show_bug.cgi?id=285743 This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of korganizer (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months. Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input. |
