Subtracting times

[Bob]

Hi, and thanks
For the life of me I can't figure this out, and I know it's simple.
in cell a1 have the time 09:22:45am
in cell a2 have the time 09:23:55am
I want to subtract and in cell a3 have the answer of 1:10
Do I have to format the cells as something else and not time?

Thanks Much
Bobby
