Formula
Result Time = Start Time + (Hours × 60 + Minutes)
If the result crosses midnight, the time simply wraps around to the next or previous day — e.g. adding 3 hours to 11:00 PM gives 2:00 AM.
Examples
9:00 AM + 2h30m = 11:30 AM
9:00 AM − 2h30m = 6:30 AM
11:00 PM + 3h00m = 2:00 AM (next day)
1:00 AM − 2h00m = 11:00 PM (prev. day)
