How the time calculator works

Times are converted to seconds, added or subtracted, then turned back into days, hours, minutes and seconds (1 day = 24 hours = 1,440 minutes = 86,400 seconds).

Adding time to a date uses your local time zone, so crossing a daylight saving change keeps the clock time right.
