How to add a given timestamp to midnight?

Write a function named getTimePeriodRepresentation which receives a float as input. The float received by the function represents the timestamp (seconds since midnight) of an observation as well as the time period interval p that must be used to generate a time period string. The function returns the Nth-minute time period of the observation in HH:MM AM/PM format. The value of p (Nth-minute) can be 5, 15, 30, or 60.

function is getTimePeriodRepresentation(timestamp, p)

input into the function: (300.125, 5) returns : '12:05 AM'

(26850.431, 60) returns: '07:00 AM'

(49550.032, 15) returns: '01:45 PM'

(49550.032, 30) returns: '01:30 PM'

base = datetime('today', 'Format', 'hh:mm a')

Now add time offsets to base.
