this is infact, what I do[1] :) sorry if I wasn't clear. I run ntpd
on 1 machine(sometimes 1 machine per network). This syncs to some
external source, and ntpdate runs on all the "other" machines which
sync to this one local system. But I really only run ntpd on this
machine so I can sync other machines to it.

As above, only 1 system sync's to an external server, and it is
a .gov server, time.nist.gov or something. Since it's a government server,
run possibly by at least a couple fractions of a cent from my tax dollars
I think I have a right to sync against it, they can always block me if
they want though. I used to sync against other servers, theres a list
of them somewhere, but the list seemed to change a lot and even with
multiple servers in the list sometimes after 4-6 months all of those
servers were down/not responding anymore. I think the .gov one won't go
away.
