GPGGA has one added benefit: If you turn on clockstats you get a log of
the current position every second, this is perfect input for a
statistical averaging of the current antenna position. :-)
It doesn't have the date.
GPRMC is the only one I know of with both time and date.
So you should really have GPRMC for the initial sync (and possible large
jump), then GPGGA afterwards. :-)
Using the default max 1000 seconds offset, the date isn't really needed,
except to sanity-check the current local date.
