What is the best sentence to use with NMEA?

[Hal Murray]

GPZDA doesn't have a valid/bogus flag
GPRMC only has 2 digit years.

I have a NMEA device that is in the old era.
   $GPRMC,030328,A,3726.0814,N,12212.2610,W,000.3,346.3,160298,015.5,E*60

I should be able to calculate the offset, but I haven't got my head around it 
yet.  It's some mix of year truncation and GPS epoch.

If it did the GPS fixup right, it would be off by 619315200 seconds. ntpq -p 
says it is off by 59184000.
