Re: Regarding NTP offset.
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.

Re: Regarding NTP offset.
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.
