I have a problem with the time not updating on the lockscreen. It shows the time from when I use the lockscreen the first time after a reboot, after that it's just stuck on whatever time it was when I booted, though the desktop and system clock updates as usual. Not even a killall qtlockscreen changes the time displayed..

Edit:
Nevermind, it was the TimeFormat that was wrong, changed HH:MM to hh:mm, now it works fine.
