Morphology

eastern + standard + time

Each constituent contributes transparently: 'eastern' specifies the region, 'standard' indicates the official/normal convention, and 'time' refers to clock time, so a learner can infer this is the official time used in the eastern region (i.e. a time zone). This compositional naming pattern for time zones is common cross-linguistically, making the phrase readily understandable to a B1 learner who knows the parts.

Etymology

Eastern Standard Time comes from the idea of using one standard time for the eastern part of a country so people there set their clocks the same way. So Eastern Standard Time means the official clock time used in the eastern part of the United States.
