Use of Trimble Thunderbolt for GPS clock time source?

Anyone know if the Serial DB-9 port on a T-Bolt can provide us with GPS
clock time for a dual purpose? We use the 10 MHz now to create a TCXO
replacement in a VHF radio (makes for good simulcast clock lock so they are
all on channel) but now we need to synchronize the rest of the system using
store-and-forward of our TCP packets and make everything on time.  That
needs real GPS clock time and we don't want to buy another GPS RX for each
location.  Can we get both signals from one T-Bolt?

Yes it is easy to set up.  The Thunderbolt users the "Palisade" NTP
reference clock driver.
Then of course NTP will keep all your systems running on the same time.

It sounds like maybe you were going to invent your own network based time
sync system?  Don't do that.
