Hi ,

Time Difference between NTP Server and client is more than 5 seconds considered to be Crtitical.

Provide more details from server end like ntpq -p ;date & cat /etc/ntp.conf .

You can stop the NTP Service in client , manually Sync system time With NTP Server and Start the NTP Service will do the needfull.

Be careful about restarting NTP on servers. If you are not running any databases and/or time synced software, it wil be fine. However, most modern databases may require repair if the system time of day changes while running. A reboot will accomplish an NTP restart while shutting down the applications and databases in an orderly manner.

If your NTP service is drifting by more than a fraction of a second, you'll need to troubleshoot the reason. Do you see a of of NTP errors loged in syslog.log? Are you connected to your NTP reference through an unreliable connection? ntpq is the tool to start troubleshooting the problem.
