BTW, GMT is long gone as an official time standard. It is now called UTC which cryptically stands for "Co-ordinated Universal Time". So why is it UTC and not CUT? Standards body politics. It was the only one that nobody wanted, so that's what the agreed upon. The French wanted it to be TUC to match the French translation, the English speaker wanted CUT - we got UTC so no one is happy or everyone is equally unhappy.
