This is, or should be, a FAQ.
NMEA output is unusable as a time source.
The time in an NMEA sentence tells you at what time the stated position
etc. was measured, but not the current time. There is no time marker (no
*now*) in NMEA.
Experimentally finding an offset and fudging it away (hoping that the
offset will be constant) just cannot be a substitute for a proper and
well-defined time source.
