.. and I have one reporting -22!  Hence the need for more investigation 
and understanding.

Here's a typical line:
  56006 12567.480 0.003754344 7.420 0.000799395 0.036695 6

Precision of the fields:
day: integer
second: 3 digits, milliseconds
offset: 9 digits, nanoseconds
drift compensation: 3 digits (of parts per million)
estimated error: 9 digits
stability: 6 digits
polling interval: integer

Yes, for -19, but what about my -22 system?  In any case, I was simply 
suggesting that the same data should be available through ntpq as through 
loopstats.  The precision with which that data should be reported is not 
an issue in the bug report.
