[time-nuts] Trimble Thunderbolt no longer determines the correct date

Caught it. Some Trimble Thunderbolt TBoltmon.exe screen shots attached:

GPS WN 1959 TOW 604799 (July 29, 2017 23:59:41) advanced to
GPS WN 936 TOW 0 (December 13, 1997) instead of
GPS WN 1960 TOW 0 (July 29, 2017 23:59:42).

1960 - 936 is 1024 weeks, as advertised for this version of the TBolt GPSDO. Note this happened at 23:59:42 UTC as expected (that's GPS midnight - 18 UTC leap seconds). I did not expect the reported 2.75 us 1PPS phase change and will look into that.
