Notice that this thread is cross posted to comp.protocols.time.ntp -

NTP is the protocol that's used to for "getting the atomic clock time 
via internet".  In reality when you get the atomic clock time from the 
internet you are talking to an ntp server that (unless it's one of the 
government ones that actually talks to an atomic clock) is most probably 
getting it's time from GPS.

The original poster that started this thread was setting up such a 
server (it's relatively easy I have one at home).

OK enough cross posting for now.
