If you have a GPS timing receiver (different from navigation receiver),
with a PPS output, one edge of that pulse should be accurate to within
50 nanoseconds. A serial output will tell you which second is marked by
the pulse.
Getting time into a computer without losing some of that accuracy can be
quite difficult.
