To sync with our NTP server.:-
First disable the ntpd daemon
/etc/init.d/ntpd stop
now you can sync using the command
ntpdate -v 91.192.194.59
In order to automatically sync with our NTP server :-
Our NTP server is at : 91.192.194.59
If you don't have ntp, you can install this on your server using your package manager (usually yum or apt-get).
Edit /etc/ntp.conf; remove any default servers (comment out) and add:
server 91.192.194.59
Then run:
/etc/init.d/ntpd restart
You will now automatically synchronise with our time server.
