Dave, again many thanks for that. It is at least encouraging to know that
the observation is not an unusual one, and has been seen many times
before, and I would not want you to waste time going over old ground.
Indeed, I am one of the many people who _may_ be subject to an
asymmetrical delay, and am therefore living a few milliseconds differently
to the rest of the NTP world!
