Fred, you have helped me but there is still a a problem when
subtracting date and time. It gives me a 1 in the month value when it
is the same month and there should be a 00 there. I have typed my
method and following my method I did find another example but it is
only for hours.
The only thing I did differently was put it in the format of mm/dd/yy
hh:mm:ss however when I have 8/21/2009 11:00:58 PM - 8/1/2009
11:00:50 PM Typed in the formula representing cells =B8-B7 It gives
me this value for elapsed time 01/12/00 16:45:32 there should not be
a 1 in the mm value.
Fred I found this instruction in excel but do not think that it will
solve my problem.
Calculate elapsed time (subtract time)
Elapsed time is the difference between two times. Suppose that you
want to calculate the elapsed time of a practice marathon run that
you started at 10:24:00 AM and that ended at 2:13:36 PM, measured to
the second.
Do the following:
In cell A1 (or any other cell), type the end time. For example, type
10:24:00 AM.
In cell A2 (or any other cell), type the start time. For example, type
2:13:36 PM.
Tip Make sure that you include a space between the minute value and
"AM" or "PM."
In cell A3, type =A2-A1.
On the Home tab, in the Cells group, click Format, and then click
Format Cells.
In the Format Cells dialog box, click the Number tab.
Under Category, click Custom.
In the Type box, type [h]:mm:ss.
Tip You can also show the results in minutes by setting the format
to [m]:ss.
Click OK.
In cell A3, Excel displays 3:49:36 (or 229:36 if you used the format
[m]:ss). Top of Page

I changed the format I want to display the difference in dd/mm/yy
hh/mm/ss The cell values are
In cell A1 (or any other cell), type the end time. For example, type
10:24:00 AM.
In cell A2 (or any other cell), type the start time. For example, type
2:13:36 PM.

Let's get the formatting down first.
Enter =now() in an empty cell.
Right-click on the cell, choose Format Cells...
Based on your post, you should see
mm/dd/yyyy hh:mm
in the Type: box
Add the :ss to the format.
Does this now display the date/time the way you want?
If so, copy this format to your other cells.
Regards,
Fred
