 Adverbs of time /ظروف المكان 

An adverb of time is a noun in the accusative case,  مَنْصُوبٌ, that indicates the moment of the action.

Ex, يبدأ الموظفون أعمالهم صباحًا وينتهون منها مساءً. / The employees start work in the morning and finish it in the afternoon.

مساءً     and صباحًا   are both adverbs of time.

To define the moment of time more precisely, the adverb of time is annexed to the noun or the nominal group or verbal one that follows it.

Ex, متى استيقظت؟ / When did you wake up? استيقظت قبل الفجر / I woke up before dawn.
