ntpd wierdness.

[Ian FREISLICH]

Hi

ntpq/ntpd appear inconsistent since at least r284659, reporting my
refclocks as false tick and the other selected for PPS, but not
time source:

The Oncore GPS are slightly wierd in they almost always start 32000ms
ahead on the first time read from them after reset and then correct
themselves resulting in huge jitter at ntpd start, but then with
the previous version, the refclocks were always selected as pps.peer
and sys.peer.

Now, even though the refclocks have settled down, the peer selection
seems a little strange.  At least not what I'm used to seeing.
