To be slightly more pedantic, GMT stands for "Greenwich Mean Time", and refers back to when Brittania ruled the waves - at least some of them. In order to navigate the oceans, one needed to know how far east or west of your home port you were. Greenwich, just east of London, was (is?) the site of the Royal Observatory, and given that navigation and astronomy have been linked, Grennwich was taken as the origin east or west. Hence, 0 degrees of latitude refers to the imaginary line running from north to south pole passing through Greenwich.
Every 15 degrees west of Greenwich corresponds to an hour later in local time, and each 15 degrees east is an hour earlier. (360 / 24 = 15).
By definition, GMT cannot have any daylight savings time adjustment applied to it. Now if the jolly citizens of England want to have daylight savings time, then they can - but then that are not on GMT - but probaby something called British Summer Time.
And to be truly pedantic, GMT no longer exists - the standard for the prime meridian is "UTC" Universal Time Coordinated (we can thank the French influence on the standards bodies for the strange word order). It is sometimes referred to in military circles as "Zulu Time", since each 15 degree time zone has a letter associated with it, and omitting "I" and "O" (since they get confused with the digits one and zero), you start wiht Z = zulu in the international phonetic alphabet, and then A , B, C . . . as you move east. When I use to live in eastern Australia was Kilo (K) time at 10 hours ahead of UTC.
Gasp. Didn't mean to stretch that out into a history of time zones.
