Re: ntp-server doesn't sync time correctly?

[Alexis Huxley <ahuxley@gmx.net>]

As someone else suggested run 'ntpq -p' or quicker is
'ntpq -pn' and look for a '*' in column 1 of any row; if
none then you're not synced with the server. 

Another common problem is that if your collection
of machines are on a private LAN and their gateway
machine has only a transient connection (even if
disconnect/reconnect is very very fast as with some
DSL connections) then xntpd does not handle this
well and requires a restart on the gateway machine.
If this is your case then switch to chronyd instead
of xntpd on the gateway; the others can continue
to use xntpd.
