Murray,

I dunno how you lost contact with DCN1, since you have to go through there
to get to this host. If your clock reference is anywhere close to GOES,
you should be a lot closer than "a few seconds." Mumble a TCP connection
to DCN1 on port 15 and look at the table that comes back. The "Offset"
column shows the offset, in milliseconds, between our local fuzzies. Host
15 is the WWVB clock, host 14 the WWV clock and host 11 the GOES clock.
Host 9, often far out of whack, is a 4.2bsd Sun with either a fractured
crystal or an hourglass. The dispersion in all the hosts is seldom more
than a few tens of milliseconds. There is a systematic offset between
the WWV clocks and the GOES clock of about 50 milliseconds which we have
not been able to explain.
