Morphology
GMT = Greenwich + mean + time (semi-transparent) = G + M + T
GMT is a straightforward initialism of the phrase 'Greenwich Mean Time'; a learner who recognises the base words can directly derive the meaning. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]
Etymology
GMT stands for Greenwich Mean Time, named after the town of Greenwich in England where the line of 'zero degrees longitude' runs. Mean here means 'average', so GMT is the standard clock time from that place and became the base time people use around the world.
