As soon as I can see ntpd use GPSD_JSON I'll work on it directly.  I've
never seen it work at all.

Another of my complaints about the new GPSD_JSON driver is it will
flip-flop from GPS serial time to PPS time and back with no warning.

Note this in refclock_gpsdjson.c:

        /* now aggregate TPV and PPS -- no PPS? just use TPV...*/

That will lead to mysterious problems like 20mSec jumps.

And note that code never reports the big decision it just made.
