Working with time
Durations are turned into seconds, added or subtracted, and turned back into days, hours, minutes and seconds (1 day = 24 h, 1 h = 60 min, 1 min = 60 s). Decimal values work too: 1.5 hours is 1 hour 30 minutes.
“Add time to a date” follows the calendar, so adding 8 hours to 10 pm gives 6 am the next day.
