Completing the sentence shows that the time shown is quarter past in the morning.
How the time is determined:
The given time is 9:15 a.m.
This abbreviation, a.m. is the Latin "ante meridiem."
It translates to "before midday." This is the time before 12 noon.
On the other hand, 9:15 p.m. indicates that the time is after 12 noon, which comes before 12 a.m, and p.m refers to the Latin "post meridiem."
Thus, the time indicated above is quarter past 9 in the morning or 15 minutes past 9.
