You are assuming that most users of this group are on Eastlink, and that may 
be true for all I know.  However, Aliant users have quite a different 
"geography".  Here'e the reult of a quick check I just did:

		timeserver.dal.ca		tick.utoronto.ca		time.nrc.ca
		hops	avg ping	hops	avg ping	hops	avg ping
>From Aliant	30	72.2		19	75.4		15	60.7
>From Eastlink	11	10.7 (!)		19	85.8		17	69.7

The above looks great in my mail program, and probably looks terrible in 
yours.  The ping times are, of course, just what I got now, not meant to be 
typical in any way.

Anyway, Dal is a great choice for Eastlink users, and a lousy one for Aliant 
users.  Of course, Donald's point about ntp's ability to compensate for 
network latency is quite true.
