Dear All, Thank you for the many responses regarding the difference between GMT and UTC.
Let me see if I've got this right... To all intents and purposes the two are the same. UTC is more "acurate" (or should I say regular) because it's based on the frequency of some arbitrary atom that has nothing to do with rates of rotation of the earth or any other astronomical rhythm. It's used by the scientific community because of its acuracy, but not by anyone else, and whenever it strays too far from GMT, leap seconds are used to bring it back in line. Hmm... So who's the master here, and who the slave?! David Higgon London, not too far from Greenwich ;-)
