    There's nothing wrong with rdate, but the NTPv4 protocol includes tests and
    detection measures for broken clocks which eliminate most "falsetickers".

    Running ntpd will try to generate an ntp.drift file which will compensate for
    the drift of the native clock, so if the problematic system is off by a
    consistent factor, ntpd can compensate for that, within limits.

    On the other hand, if the drift is variable or the clock hardware is just
    completely busted, then I'd replace the motherboard, or at least break apart
    the system and look for bad solder joints, leaky caps, etc, and try
    reconnecting everything again....
