If you just do a search for "Time Synchronization" on google, that will give you lots of tools, quite a number being shareware or freeware. As Sylvain said time related service is already running on Unix boxes. And for NT et al, you can use something known as AboutTime (this can act both as a time server & time client), and another one is Dimension4. Both can be easily searched through google.
