Answer 1

You can easily do this with the normal "Time" data type - just change the format!

Excels time/date format is simply 1.0 equals 1 full day (starting on 1/1/1900). So 36 hours would be 1.5. If you change the format to [h]:mm, you'll see 36:00.

Therefore, if you want to work with durations, you can simply use subtraction, e.g.

A1: Start:           36:00 (=1.5)
A2: End:             60:00 (=2.5) 
A3: Duration: =A2-A1 24:00 (=1.0)
