[MacTUG] a drifting network time

[Dawn Keenan]

I'd recommend ntp1.uwaterloo.ca or ntp2.uwaterloo.ca. While they may be 
the same hardware as the campus name servers, IST could theoretically 
move the service anywhere.

When I was in CS, we had a local NTP service running on one of our 
servers and used it as the time source for both AD and the Macs.
