1) Stop the xntpd daemon

The xntpd daemon is managed by the System Resource Controller (SRC).

To verify that the xntpd daemon is active : lssrc -s xntpd : status

should be "active"

To stop the xntpd subsystem : stopsrc -s xntpd

Note : xntpd is automatically started in /etc/rc.tcpip. To verify this :

cat /etc/rc.tcpip | grep xntpd.

2) Modify the /etc/ntp.conf file

Put the following lines in the /etc/ntp.conf file :

server <IP address or FQDN of timeserver> prefer

driftfile /etc/ntp.drift

tracefile /etc/ntp.trace

3) Restart the xntp daemon

To restart the xntpd daemon :

startsrc -s xntpd

4) Check status of time synchronization

To check the status of the time synchronisation, use the ntpq utility.

ntpq -i : start ntpq interactively

ntpq> peer

remote refid st t when poll reach delay offset disp

==============================================================================

* .PPS. 1 u 863 1024 377 0.92 0.160 0.47

The "offset" field displays the difference (in milliseconds) between the

system time and the reference time.

Type "quit" to exit the ntpq utility.
