Assuming your values are in A1 and B1 respectively, then just try =B1-A1 and
format the cell as time.

I have two columns. Both have a time format of NN:NN:NN. I would like
to calculate the difference. For example, if I have 10:02:01 and
10:03:05, I want to know that the difference (amount of time) is
00:01:04. Is there someway I can do that in Excel? Thank you.
