Hi,

It is unlikely that the machine in question drifted forward in time if ntpd
was running. Have a look at the logs /var/log/messages it should contain the
ntpd log messages which will help you determine what happened to the time.
Also check that ntpd is running with:

"service ntpd status" and also "chkconfig ntpd --list" will show the startup
position of ntpd
