So what do you do when your menubar clock freezes?
This [ kill -15 185 ] seems a little harsh (185 was the pid of the SystemUIServer application that manages the menubar).
But nothing else I tried worked. I tried:
- toggling the settings for the clock in the Date/Time PreferencePane
- toggling the settings for the clock in the International PreferencePane
- editing the plist file (~/Library/Preferences/com.apple.systemuiserver.plist)
Hmph. Then restarting the SystemUIServer wasn’t so simple. I would have thought it was a daemon process, and would restart itself. Nothing doing.
% /System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer
Hmph, again.
If this comes to bite you, let me know if you find a different solution.

I think my method has been to force-relaunch the Finder, and when that doesn’t work, log out and back in. Failing that, reboot. A manual kill and restart doesn’t sound so bad, come to think of it. If it happens to you again, maybe try kill -HUP instead of kill -TERM?
Force-relaunch of the Finder didn’t work. Logging out was inconvenient at the time, though I am sure that would have worked. Kill -HUP or even kill -9 failed as well. I guess I could have mentioned that.
