    I've seen this behavior many times on my DS3100's running ultrix V4.0
    and the DEC-supplied ntpd.  I went to xntp, same results.  If anyone
    knows more about this I'd appreciate hearing about it.

Could this have anything to do with the mysterious clock-stopping
problem people were reporting for their DECstations?

(This is a little disturbing, since our central campus server is a
DS3100 as well...)

In any event, I suspect that a suitable workaround for the moment is
to add the line
    /usr/etc/ntp -s -f ...hosts named in /etc/ntp.conf...
to rc.local before ntpd gets started.
