Morphology

time + zone

The meaning 'a region sharing the same standard time' is directly derivable from combining 'time' (clock/measured moments) with 'zone' (a region or area): it is a transparent noun+noun compound that describes a region defined by time. This compositional pattern is common across languages (e.g., Spanish 'zona horaria'), so a B1 learner who knows both constituents can readily infer the MWE's meaning.

Etymology

The compound noun time zone comes from the idea of cutting the world into bands so each band uses the same clock time. Imagine the globe divided into slices, each zone sharing the same time, so the phrase means 'one of the regions where the same time is used'.
