Assuming that the Dates are in column A & the Charge Times in col B, and the
headings are in row 1:

To find the difference in charge time between row 3 (7/9/06 19:00) & row 2
(7/9/06 7:55) use the following formula in C3:

=(A3&B3)-(A2&B2)

Then simply copy on down. Initially, if col C isn't time formatted you will
get 0.461805555 as the answer because it is formatted as General. Make sure
that row C is time formatted (row A should already by date formatted & B
should already be time formatted).

7/11/06 13:00
7/12/06 3:40
7/13/06 2:00
7/13/06 23:50

I would like to find the difference in charge time in a new column. How
would I go about doing this?
