Re: [gpsd-dev] ✘$GPGST busted time

I remember seeing something in their firmware about the '$' of
"$GPZDA" being intentionally aligned to the top of the second because
that can be triggered just by the clock; everything else in the middle
has variable timing depending on the navigation solution.

GDB has a 'break' feature; why doesn't it have 'fix' too?
