server <server_ip address>
server                   # Serve the local clock if no other 
source is available!
fudge  stratum 10   # Make sure that no one will use this if 
a better (lower
                                               # stratum) server is 
driftfile /etc/ntp.drift
broadcastdelay  0.008
logfile /var/log/ntp.log

Your server's stratum will be calculated automatically as soon as it 
synchronizes with its
server.  If it is not synchronized it should operate at a high stratum; 
e.g. 10 so that no one
will use it if any lower stratum server is available.  (If your server 
is not synchronized it almost certainly does not have the correct time!)
