Questions
How do I add hours to a time?
Enter the start time, choose Add and type the hours. If the result passes midnight, the date moves to the next day.
Can I subtract minutes from a time?
Yes. Choose Subtract and enter the minutes. The result shows the new time and the date.
Does it handle daylight saving time?
Yes. It counts real elapsed time in your time zone, so adding 24 hours across a clock change can land on a different clock hour.
