The noun is Time.  The C* is an adjective, coordinated or coordonné.  It 
appears the abbreviation is not in correct word order for either of 
French or English:

Why? Repetition? Is PST time also annoying?
Universal Time Coordinate time is not really repetitious anyway, since
the noun is Coordinate. And UTC time means the type of time defined by
UTC-- since there are lots of other types of time one could use--
including decimal time ( 100 sec/min/ 100min/hr, 10hr/day)

They are not perfectly identical. The difference is however less then 
one second;

GMT is mean solar time.
UTC is TAI (atomic time) + leap seconds.
