In our company, are using Linux server. The problem is that there is a time difference of about 20 min after 10days from stadard time. Two of the are dual processor xeon server. How is this posssible and any idea why this is happening ? the reason every min should be synchronize is that i am trying to introduce a networking monitoring based on MRTG ........... any ideas ?
Try NTP (Network Time Protocol) That should correct that in a easy way, but the behaviour iis really strange, maybe a NTP miss-configuration, You should ask the system admin(s) to check that, And check if there's already a NTP or something like on start up.
If tehre¡s not a NTP service, well you can set it to sync the RTC periodically.
