Answer 1

Assuming that the user is entering strings like "01:12", you need to convert (as well as validate) those strings into the number of minutes since 00:00 (e.g., "01:12" is 1*60+12, or 72 minutes), then subtract one from the other. You can then convert the difference in minutes back into a string of the form hh:mm.
