Need to sum up HHMMS AM/PM DD/MM/YYYY and a HH:MM:SS.

Using datetime

import datetime


start_string = "08:31:27 PM 01/02/2023"
total_time_string = "01:22:14"
format_string = "%I:%M:%S %p %d/%m/%Y"
start_datetime = datetime.datetime.strptime(start_string, format_string)
hours, minutes, seconds = total_time_string.split(":")
total_timedelta = datetime.timedelta(
    hours=float(hours), minutes=float(minutes), seconds=float(seconds)
)
end_datetime = start_datetime + total_timedelta
print(
    f"{start_datetime.strftime(format_string)}, {end_datetime.strftime(format_string)}"
)

Output:
08:31:27 PM 01/02/2023, 09:53:41 PM 01/02/2023
