I was sent a NMEA log of a Garmin GPS12 (f/w 4.60) showing
the strangest leap second trace yet. Has anyone else see this
before? In the ~15 seconds below, note:

- double 235957
- missing 235958 for the RMC sentence
- no second 235960 for either sentence
- strange 000059 for the BWC sentence
- missing 000008 BWC sentence
- gps lock lost from 235957 to 000043
