Dividing af formula for elapsed time with a fixed(static) time

Hi all,

First post here, and in a bit of a tight spot.
I have a formula:
=NOW()-TIME(8;0;0) to calculate time elapsed at work
that I want to divide by hours we are open at work; a fixed value of 12:00:00 (hrs)

When I divide them and want it in percent, I get a huge number (8388459,8% e.g.)

If I plot the formula's result in manually I get the correct percentage out. Both cells are the same format in time.

Could you help me out? I've searched as much as I could, and the only thing I find is a macro to plot the result of =NOW()-TIME(8;0;0) in another cell.

Thanks!

Christopher

Thanks guys it worked! I used the =NOW()-INT(NOW())-TIME(8;0;0) which worked. The two formulas you mentioned, Olly, gave me some erroneous times.
Thanks again
