I think you asked the wrong question, so you got the question to the
answer you asked and not what you wanted to know.

You asked whether Lady Heather can set PC time, the answer is yes but it
is a crude way to set the time.

What you really wanted to know is how to get time from a GPS receiver into
the PC, and the answer to that is that gpsd has a driver that can
communicate with a Thunderbolt (Palisade driver), and gpsd also knows how
to communicate with a Thunderbolt.  So use ntp directly to communicate
with the Thunderbolt.  Lady Heather is an awesome program for doing lots
of things with a Thunderbolt, but disciplining the system clock to follow
the GPS receiver is not really one of those things.
