Hands down, then best way to synchronize clocks over a network is to use
NTP (Network Time Protocol).  We use this to keep our machines in sync within
our own local netowork and throughout Sun.  My fourteen servers stay within
a few miliseconds of each other and my time server stays within a few miliseconds
of Sun's time server.  If you don't want to (as we don't) use NTP on all of your
systems, the others can rdate to assorted time servers.

NTP is public domain stuff.

 "Mars is essentially in the same orbit ... somewhat the same
   distance from the Sun, which is very important.  We have seen
   pictures where there are canals, we believe, and water.  If
   there is water, that means there is oxygen.  If oxygen, that
   means we can breathe." -- Vice Pres. Dan Quayle on Mars
