[comp.sys.apollo] xntp with only Apollos

When I mentioned at the local San Diego Apollo users group meeting today
that we were using xntp to synchronize node clocks on our multi-ring
network, it generated a lot of interest.  But I couldn't answer a couple
questions users had.

Our Apollos synchronize to our campus machines which are on the Internet
and they ultimately synchronize to a machine with a WWV clock somewhere
out in netland.  Most of the users at the meeting are not connected to
the Internet.  What clock would they ultimately synchronize xntp to?

I suggested two possibilities, but I don't really know if either is
possible: (1) Pick your most accurate node and call that the master. (2)
Buy a hardware clock and connect it to one of the Apollos somehow.

Are any of you using xntp where only Apollos are involved, and providing
your own master clock using these (or any other) methods?  Can you
provide details that I could pass along?  If you have connected a WWV
clock to an Apollo, what's the interface, manufacturer, price, etc.?

Thanks for any suggestions,
