It's not necessary to use refclock_process() if the driver creates
its own l_fp timecode timestamp and uses refclock_process_offset(). I
was considering removing refclock_process() when I added the rollover
workaround to the trimble driver, but then I read this:

Are there any known examples?

It's impossible to tell. When a device will roll over is, because of the
pivot-date trick, not a function of its hardware type but of its
firmware release.

How many of the NMEA devices have GPS rollover problems? (either now or soon)

These are my opinions. I hate spam.

Right, not the same problem.

The problem I'm interested in is not Y2K, it's GPS rollover. 1024 weeks is
