1h 30m 0s plus 0h 45m 0s equals 2h 15m 00s (8,100 seconds total).
How it works
Both time values are converted to a total number of seconds. Depending on the chosen operation, the second value is added to or subtracted from the first. The resulting seconds are then converted back into hours, minutes, and seconds. A negative result from subtraction is displayed with a minus sign, meaning Time 2 was greater than Time 1.
