Mavericks 10.9.5, on a mid-2012 MacBook Pro, Unibody.

This function used to work well for me - whatever Location services determined to be my current location would make the Time Zone change in the Date/Time PrefPane.

Now it does not. If I turn off the function, and switch it on, Date/Time successfully receives my current location, but the Time Zone will not move accordingly.

I decided to look in Console, system.log, and found the following:

First, it reported this sequence twice:

Jul 13 22:50:14 macintosh com.apple.systemadministration.writeconfig[104]: ### Restricted client at path /System/Library/PreferencePanes/DateAndTime.prefPane/Contents/Resources/TimeZone.prefPane/Contents/Resources/TimeZoneAdminTool

Jul 13 22:50:14 macintosh com.apple.systemadministration.writeconfig[104]: Warning: Exception caught during decoding of received message, dropping incoming message.

Exception: <NSXPCDecoder: 0x7f8fde008600> received a message that is not in the interface of the local object (setMachineDictionary:forKey:inDomain:authorization:result, dropping.

Jul 13 22:50:14 macintosh TimeZoneAdminTool[431]: ### syncProxyWithSemaphore error:Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application.

On the third attempt, it dropped the entry ending in "Couldn't communicate with a helper application", but added the following:

Jul 13 22:50:14 macintosh com.apple.preference.datetime.remoteservice[423]: !!! ASSERT FAILURE: Selected city on the map is different than what we expect to be selected !!!

I've done a lot of searching for anything about TimeZoneAdminTool, and NSXPCDecoder. Haven't really seen much.

Thanks for looking
