[time-nuts] Trimble GPS ignored the leapsecond!

Hello all,

I had 3 PC's logging 3 GPS's for the leap second insertion.

A Motorola GT+ showed the leapsecond as "60" and is currently in sync with 
UTC.

A Trimble SV6 GPS did NO leapsecond correction in NMEA mode, rebooting the 
GPS in TAIP mode - it is now in sync with UTC!

The following is a Garmin 18 LVC, to make it easy to read I have edited it 
down to just the relevant time info. note how $PGRMF relates GPS time and 
UTC time.
