Ok. I'm looking at a client that needs to keep their server time
close as reasonably possible (within a minute) of the actual time of

what the simplest setup should be, ie:
What server(s) should I be using for sync?
Should I just run it from a cron every 20 minutes or so?
I do wish it would prefer the time server offered by DHCP:-( I'd
rather sync one computer over the Internet, and the rest off my local
network.
how large is your local network? arguably you should be using at
least two, and ideally three, timeservers on the local network; ntp
works ok with only one source of time, but times will converge much
more quickly with multiple sources of time.
don't run 'ntpdate' from a cron job; that defeats the whole purpose of
running ntpd.
and this won't work if ntpd is running ("socket already in use" or
something similar).
