Thanks for using Apple Support Communities.
TCP port 123 is used to communicate with a network time server.
If your router is blocking this port it will never set the time.
For more information on this, take a look at this article:
Apple TV: TCP and UDP ports and protocols used
http://support.apple.com/kb/ht2463
Also it needs an active internet connection.

Best of luck,
Mario
