This is the ntpq -p output from 2 machines connected to Garmin GPS's.
The machines ip's of the 2 machines are 192.168.0.28 and .29. They
are about a millisecond apart! That's no better than the server
without the GPS. What did I do to deserve such lousy performance.?
server 127.127.20.0 prefer minpoll 4
fudge 127.127.20.0 refid GPS flag3 1 flag2 0 time1 0.0
and the machines are peered together.
