NTP time reset?

My understanding of the working of NTP is that when the system's time is way-off compared to that of the time-server, there will be no synchronization until the system time is manually set to within a couple of seconds of the time-server's time.

Perhaps some abnormal event disturbed host chbsc301's idea of time? Just try a manual reset and see if it resyncs with the time-server.

Alan.
