Version: (using Devel) Installed from: Compiled sources 1) set the short date format to MM/DD/YY (on systemsettings) 2) start korganizer and add/edit an event 3) focus the start/end date 4) press UP/DOWN key on keyboard The year will loose the "0" digit and from the current year (2008) it will go to year 8... 2000 year ago :-) and the day will be changed. If the date format is dD/mM/YYYY, UP/DOWN will change ONLY the day (which is correct), but the year doesn't change!!! Thanks to doviende for reporting it on http://techbase.kde.org/Contribute/Bugsquad/BugDays/KDEPIMKrush1
I only have these three options: DD.MM.YYYY dD.mM.YYYY YYYY-MM-DD Can you check if you still have the DD.MM.YY option in >=KDE4.2?
Fixed by David Faure in commit 928366 in trunk, and 928370 in 4.2 branch.
