Yes, I know it's a complex protocol. However, I didn't put the local
clock (fudge?) on the configuration, hoping it would only take the
time server into account.

I am leaving them and seeing.
Funny thing, my machine, which was in sync yesterday, is not in sync
anymore today. The offset starts increasing and increasing until it's
several minutes in difference.
I've read something about ntp requiring CONFIG_SECURITY=y and
CONFIG_SECURITY_CAPABILITIES=y on kernel 2.6. They are both activated
on my machine.

Yes, I could put all those time servers on all config files, but is
this the best approach for a network? I thought I could let one of
them synchronize to several servers, and let all others synchronize
from this one. The jitter is minimum, as they are on the same network.

This is what I'm trying to avoid. ntpd is a cleaner solution, as it
records the clock drift instead of just updating the clock every X
hours. In fact, most 'cron solutions' I see are ugly workarounds.

Thanks for the reply.
