I originally installed 11.1 using the default language selection, English. I then changed to German for my wife, and wanted to change the digital clock display to the 24 hour.In the root display it is in the 24 hour format, in the KDE desktop settings it is also shown in the 24 hour format, but on the user display my wife uses it's shown in am/pm format. I can't find any possibility to change the format.

I also installed 11.1 on a usb hard drive to use as my test version for trying new software or settings. I installed in German from the start, and the 24 hour format is shown on all screens.

Anyone have any ideas?
