Morphology
The core meaning — a time standard that applies everywhere — follows directly from combining 'universal' (applicable in all places) with 'time' (measurement of moments), so a B1 learner who knows both words will grasp the basic concept. Technical details (mean solar time, Prime Meridian) are specialized knowledge, but they do not prevent the MWE from being compositionally transparent and cross-linguistically recognizable.
Etymology
Universal Time comes from the idea of using one fixed clock in Greenwich, England, so everyone could set their watches to the same universal time. That's why Universal Time means 'one standard time used around the world'.
