Please do send them to me.  Ideally as git patches, but I'll take what
I can get.

Keep an eye on it, the gpsdd json interface is twitchy.  PPS might come
and go with the skyview and ntpd gets confused by the different precision
of the NMEA and PPS streams.  Best to also be running at least 3 network
ntp chimers at the same time.

Also spend some time on your fudges, getting them right helps convergence.
Or if you need faster convergence use chronyd.
