In this test run, the logger time stamps rolled over after 18:12:15.985:

Indeed, the time stamp overruns when 65536=2^16 seconds have passed.

OK, should not be at 18 hours, but an overrun is correct. Which firmware version do you have?

03:00:02.843;I;$POSMST,Start NMEA Logger,V 0.1.9*3B

OK, corrected in next firmware.
