Hello, the clock on the menubar is frozen. If i click on it the time updates but it is still frozen. I have tried quitting SystemUIServer and i have restarted but the clock is still frozen.
This really annoyed me and p****d me off. I rectified it by deleting the Clock.menu in /System/Library/CoreServices/MenuItems/ and replacing it with a backup one and it's fine now. Mine, at least, was triggered by exiting full-screen mode in QuickTime.
