[TenTec] GMT vs UTC

[demerson]

As several have pointed out, GMT is effectively the same as UTC.

If we're being really pedantic, there is a subtle difference involving 
partial leap seconds, and the fact that the earth does not rotate at a 
precisely constant rate.  There is a very convenient and definitive 
explanation of different time systems (including GMT, UTC, TAI, UT0, 
UT1, UT2, and others) by Rick Fisher (KE8DH)  of the National Radio 
Astronomy Observatory at
