Morphology

mountain + standard + time

The phrase is compositionally built: 'standard time' means the official/local time and 'mountain' specifies the geographic region, so the overall meaning — the official time used in the mountain region (the Mountain Time Zone) — is directly derivable from the parts. This construction and logic are cross-linguistically common, so a B1 learner who knows the constituent words will very likely understand the MWE.

Etymology

Mountain Standard Time comes from setting one official time for the mountain region, and standard here means 'official'. So the name now means the local official clock time used in the mountain states ('local time').
