[time-nuts] Thunderbolt GPS "APP" updates?

"The two apparently were manufactured within 3 months of one another."

I'd say 9 months. The firmware revision from 2.2 to 3.0 is the 
3 months you mentioned and from what I could gather ( which may 
or may not be correct) mainly changed the algorithm for handling 
carryover and unless you're without a lock for a long time you'll 
not notice any real difference. I wouldn't worry about it.
