Morphology

central + standard + time

The meaning 'the standard time of the central region' is directly and compositionally derivable from 'central' (middle/central region) + 'standard' (official/accepted) + 'time' (clock time). This region+standard+time label is a common, cross-linguistic way to name time zones, so a B1 learner who knows the constituent words will grasp the basic meaning (even if they might not know the exact GMT offset).

Etymology

Central Standard Time may come from the days when railroads needed one standard clock for each part of the country. Railroads set the same time for the central or middle region so trains and people used the same schedule, and that's why the phrase means the official time used in the central region today.
