Perhaps the 'network time server' for the region, that Apple uses, is down at this time(?)
Not sure how one would go about reporting an issue, to somewhere it would matter...
Try unchecking the box next to the automatic time zone location item & set it manually.
{Edit to add: I noticed you asked of this in an older thread, that had suggested this:
OS X Mavericks: Manage which apps can use Location Services
http://support.apple.com/kb/PH14318
And I looked into that link, but it does not explain your issue.}
The same item has occurred several times, as indicated by a few similar named topics
that come up on a search via google of those same words; here's the link to that:

You may have to set the TimeZone manually and turn off the automatic location.
This has been an issue in some places (regional, etc) since OS X 10.6.8. but
I have no way of knowing if the cause may be the same or another behind it.
However such an outage (if it could be proven as such) would be difficult to work
around; short of testing the computer in a different Time Zone to see if that network
server was working. Then you could tell if the issue is in the Time Zone you wanted
to be using, and not in the computer itself. A matter of troubleshooting.
{Since these ASC discussion are generally and simply product users who volunteer &
try to answer some varying levels of questions, an inquiry here does not constitute a
contact with Apple, Inc, directly. So please keep that in mind should nobody know
where to look (if possible) to discover an exact match to your issue.}
So, see if the clock and time zone work if you do not have the Automatic location set
and choose the location manually instead. I don't believe a reset of the System
Management Controller (SMC) or the NVRAM/PRAM may be of help; though these
do have some bearing on settings in the computer, for different purposes.

Hopefully you won't have to reset anything but the Date/Time panel in the Mac.
Good luck & happy computing!
