[Casper] set network time at startup?

[David Lundgren]

We've had the same problems with time issues on our Macs and ended up
writing a custom synchronization script. It could handle some enhancements
and possibly hooking into the system better. Right now it waits for 2
minutes before trying to synchronize on startup. We also have the script run
every day at 9am (via /etc/periodic/daily).

We use the servers in this order:
1) time.nist.gov
2) the ADC

Each computer synchronizes twice. Once for each server in the list.

I haven't tested it on Leopard yet, but I know on Tiger you had to kill
Ntpd and ntpdate in order to get the time to actually be updated, which is
why you get "NTP socket is in use." errors.

I've attached the script that we run, if you plan on using it you should
replace "time.example.com" with the server you want it to sync with.

Hope that helps, and gives you a direction to look in.
