Prepositions can introduce time phrases. For example, we use at with specific times (at 6:45 p.m.), and we use since to tell the beginning of a time period (since 1992).

Prepositions of Length of Time
The prepositions for, since, and during indicate a period of time.
FOR Use with a quantity, or period, of time.
SINCE Use with the exact beginning of a period of time.
DURING Use with the name of a period of time.
In English, “a half” comes before the time word. We say “five and a half hours,” not “five hours and a half.“
