I have a co-worker that is trying to create a spreadsheet to keep track of
how many minutes it takes to complete drafting projects. He wants to be able
to enter his start time in one cell, his finish time in another cell and be
able to get a result of how much time it took in minutes or hours in another
cell. For example, he starts and enters in a cell 2:00p.m. then in the next
cell he finished at 3:30p.m. he wants a result cell to show 90 minutes. Of if
he uses military time he wants the same results. Is there a function that
will calculate time like this?
