The NTP server (assuming you are using xntpd) won't monitor the clock
unless it's within a few seconds already. If the server starts and the
clock is already too far out of sync it won't work at all regardless of
what you do afterwards.

Best bet is to run ntpdate to sync it once then start the server.

After a few minutes (give it 5 or so) you can run "/usr/sbin/ntpq -n" and
type in the commands "pe" and "as" to see what's going on. You should see
that it can contact the firewall and acknowledges that it's a peer if
everything's working okay.

Remember...

        /etc/rc.d/init.d/xntpd stop
        /usr/sbin/ntpdate (firewall IP)
        /etc/rc.d/init.d/xntpd start
        (wait a few minutes)
        /usr/sbin/ntpq -n
        (type in both "pe" and "as")
        (CTRL-D to exit)

You should see something like...

ntpq> pe
     remote refid st t when poll reach delay offset disp

ntpq> as
ind assID status conf reach auth condition last_event cnt
===========================================================

...if everything's working well.
