Morphology
The phrase literally combines a place name (Greenwich) with 'mean' (average) and 'time', so a learner who knows those words can infer it denotes the average/standard time at Greenwich (the Prime Meridian). This is a compositional, cross-linguistically common label for a time standard, so despite being a technical term it is transparent to B1 learners.
Etymology
Greenwich Mean Time comes from Greenwich, a place near London where people kept the official clock that ships and countries used to set their time. Mean here means 'average', a steady time used so clocks would not jump with small changes in the sun, and that's why Greenwich Mean Time became the world's 'standard' time.
