I assume it was working correctly previously. If not... At least one GPS
receiver I've used is off by a second. There is an ambiguity as to whether
the time applies to the previous or next PPS. I assume that's why they got
it wrong, but maybe they are just off by one for some other reason.

I've seen Garmin 18s (probably no x) be off by a second, but that was only
for a transient. I haven't chased it. I assumed it was when recovering from
not-enough satellites. (I'm running them inside, poor signal.)
