Hi Tariq, You seem to be using debian or ubuntu. The documentation here will guide you through setting up ntp: http://www.cyberciti.biz/faq/debian-ubuntu-linux-install-ntpd/ <http://www.cyberciti.biz/faq/debian-ubuntu-linux-install-ntpd/> . When you have finished these steps you can check the system’s clocks using the ‘date’ command’. The differences between the servers should be minimal.
