Apparently the Garmin GPS 18x LVC took its time applying the new
UTC-GPS offset.  I didn't log every sentence, just the last of each
16s polling interval:

56109 719.329 127.127.20.1 $GPGGA,001157
56109 735.330 127.127.20.1 $GPGGA,001213
56109 753.320 127.127.20.1 $GPGGA,001232
56109 769.317 127.127.20.1 $GPGGA,001248

Somewhere between 00:12:12 and 00:12:32 it became enlightened.  Seems
I'll be temporarily switching off the NMEA+PPS driver in favor of ATOM
numbered by NTP, if I am still using the 18x LVC next leap second.

Cheers,
Dave Hart
