Which is why NTP prefers the source with the smallest delay. The
system I am using has servers whose delays are 51ms to 94. I can't
find any closer. On my company LAN, the delays range from 16ms to
87ms. The offsets of all these servers agree to within 9ms. Sure, I
am not going to get sub-millisecond from that, but I think it is
probably
more typical than your set-up.

Brian,

I know this is supposed to happen, but I recall seeing behaviour some time
ago where a server with a little more jitter and much more delay was
preferred, almost as if it was the jitter/offset which was the measure
rather than offset itself. I ended up adding a "prefer" qualifier.

Cheers,
David
