Editors Note: The procedure outlined below is also configurable though YaST by going to Yast2 | Network Services | NTP Client.
In order to access a time server on the network, the time sever needs to be specified for server parameter of xntp configuration file. For example, if the time server available is time.abc.net, then this can be declared in /etc/ntp.conf in the following format:
Similarly additional servers can be specified.
You can start the xntp daemon by executing following command:
The xntp daemon waits for next 1 hour until it creates a drift file to correct local computer clock. So every time the system boots, the hardware clock will be set to accurate time by referring this drift file as it specifies the amount of time the hardware clock will off over time. In this way it maintains stable computer time. Any machine running with xntp can be made as reference to other machines in the network by enabling broadcast client option in the /etc/ntp.conf file.
A command ntpdate can also be used to synchronize computer clock with the global clock as following:
