I use Meinberg's Windows implementation of NTP: http://www.meinberg.de/english/sw/ntp.htm. It runs on Windows XP through 7, as well as NT and 2000. NTP - Network Time Protocol - is an internet protocol for synchronizing time. Almost all servers on the internet use it. It isn't at all hard to set up. Windows 7 isn't optimal for time synchronization, and neither is consumer internet, but you should be able to keep within 100 ms of correct time. Linux or BSD over a well provisioned network easily does better than 10 ms. Connect a GPS with Pulse per Second (PPS) output, and you're in the low microseconds. 73 Jon LA4RT > 73, > > ...
