I received a small quantify of old field hardened Ref-Tek GPS units from 
government surplus.  I think they would survive an atomic blast :-).  They 
feature a 1 PPS pulse and an RS232 output every second that has UTC.

Several of them work.  If interested (you can have one for the cost of shipping 
it to you) let me know.
