Morphology

Atlantic + standard + time

The meaning is directly derivable from the parts: 'Atlantic' specifies the region, 'standard' indicates the official or normative system, and 'time' refers to clock time, so together they denote the official clock time for the Atlantic region (a time zone). This compositional pattern (X Standard Time) is common cross-linguistically and follows predictable English noun-modifier conventions, so a B1 learner who knows the constituent words will understand it.

Etymology

Atlantic Standard Time comes from using the same official clock in places by the Atlantic Ocean: Atlantic points to the ocean and Standard Time means the area's 'official time'. So the name now refers to the local clock used in Puerto Rico, Bermuda and the Canadian Maritimes, which is four hours behind the world's main time.
