The definitive source for time servers has always been:
http://www.eecis.udel.edu/~mills/ntp/servers.html
May I suggest a nice variety of Stratum 2 servers?
I would search around, like the other fellow mentioned, and
try to hash out the problems of updating your clock.
Once you get the scripts to work, you have to figure out
a way to run a script when the laptop comes out of hibernation,
but not the rest of the time. So a cron script that runs
every five minutes would work, but would be too often if you're
not using it and would put too much load on the public ntp servers
for such a minor problem. Plus, wouldn't a script bring
the laptop out of hibernation?
Can you just update the OS clock from the BIOS hwclock,
as long as the BIOS clock keeps the correct time during
suspend mode?
If so, you could do that with a cron script that checks
the two to see if they are different once every few minutes
or so. If they are, it updates the OS clock with the hwclock.
(As long as this doesn't wake the computer out of suspend).
Does that seem to make sense?
