Hi all,

What formula can I use to subtract 2 times so that I get the number of
minutes the one time is either ahead or behind the other. For example,
if the deadline time is 08:00 and the actual time is 8:30, I want a
result of -30 or even better, -00:30. It works fine the other way,
where the actual time is before the deadline time.

Many thanks.

Rob
