NTP time adjust consistently ~450 ms every 10 min (SSG-5, NS 6.0 r3)



  • I have verified the external NTP servers are up and updating Win 2003, which is the local NTP server. The log shows an exchange of 94 bytes with external NTP servers on session close. Windows Event Log looks ok too. I assume the lack of a negative sign in the event log means the device is always slow. Anybody else seeing this?

  • We change the update interval to 480 mins, just to not fill up the logs with time synchs and the last 3 were

    973 ms
    1974 ms
    1971 ms

    As long as NTP keeps in correct, it probably does not matter, just make sure you also change the max time adjustment higher than the default 3 seconds.  We set them to 300 seconds, occasionally we get one beyond that and it falls out of synch.  We could push it higher I guess.
