I would like to click in a cell and have the hh:mm:ss populate that cell. I
am timing how long it takes for water to drop two inches. So I have a start
time, a middle time (1st inch) and an end time (2nd inch). Then I need to
calculate the elapsed time from the middle to the end and have that
difference dispalyed in a fourth cell.

Help? Please? Pretty Please?
