On the other hand, try asking anyone around the world who isn't a Ham Radio operator or in posession of other techy credentials what "UTC" stands for and watch the blank faces... It's not even spelt the right way around for a English speaker (Coordinated Universal Time)... It's "UTC" because that's the way it is in French grammar (as in NATO becomes OTAN in France).

Besides, by the only gauge that really matters, Google has 5 times the number of hits for GMT as the number of UTC hits.
