Since a few weeks ago, KOrganizer started acting irrationally. Although an event is set to take place Sunday and Monday each week, the calendar shows it occurring Saturday and Sunday instead. I also remember that in a few cases, the event reminder was triggered around 1 PM instead of 1 AM when it's set. Anyone know what could be causing it to notice false hours and dates?

Here's a screenshot showing how the event is set to occur Sunday and Monday, but the calendar shows it Saturday and Sunday in the very other window: http://i44.tinypic.com/1e6fxz.jpg

I tried to reproduce this but I ran into other errors due to my setup (current git master). I would advise to file a bug on bugs.kde.org giving as much information as possible.

Actually, it appears I fixed it and found the problem. For whatever unknown reason, my time zone got changed. I went in YaST - Date and Time (I'm on openSUSE) and noticed my zone got set to somewhere in Africa, although the hour was still alright so I didn't notice so far. Corrected that and now KOrganizer seems to show it at the right time as well. Will post here again if the problem still persists otherwise, but it seems to be solved.
