I'm working with times (0:00:42) on Excel 2003, and cannot make a time go
negative (0:00:42 - 0:01:00). I figured out how to change the text color of
the number if the number should be negative. I now want to know how to
create a formula that is dependant on the text color of the numbers. I would
like to add the black numbers and subtract the red numbers. Is there anyone
that knows how to do this? Or better yet, is there a way to make a time go
negative?

If you switch to the 19043 date system , Tools>Options>Calculation, 1904
date system checkbox, you can get negative dates.

That's 1904, not 19043. Even Excel hasn't got there yet <g>
