Don,

The primary purpose of a Thunderbolt GPSDO is ultra-precise time (1PPS) and 
frequency (10 MHz), locked to each other, and to UTC. The good news is these 
two BNC outputs are unaffected by the date issue that you describe. The TBolt 
is designed to run fine on its own; you typically don't need a PC or control 
program to operate it.

The bad news is that if you use the Trimble TSIP RS232 interface and if you 
want the correct date & time then the software needs to be aware of the 1024 
week (19.6 year) epoch. This "GPS 1024 week rollover" issue eventually affects 
many receivers, including the TBolt, but the good news is that simple 
work-arounds are often available to address the problem.

AFAIK, the Tboltmon.exe program has *not* been updated. I still use it (when 
you're dealing with nanoseconds, calendar dates are less important).

Mark's LH program *has* been updated. See:

Didier's LCD date/time display *has* been updated:
