Thread: Time reset

  1. Time reset

    Hi,

    We have a time-server with about seven clients over LAN.
    Only in one clients it is observed that the time is reset almost daily.
    We have replaced the client with a new system. And if not daily but
    the time reset has occurred once. Below is the ntp log :

    In the third line the ppm error jumped from 0.000017 to 0.057544.
    Is it something to do with improper clock interrupts due to its misbehavior
    ?

    Venu,

    What hardware and OS is this?

    Have you seen the troubleshooting pages (known hardware and OS problems) at
    http://support.ntp.org/Support ?
