I have 3 columns of times in the hh:mm:ss format. The first column
(A1) is time recieved, the second is time staged (A2, usually blank),
and the third (A3) is time arrived. Is it possible to have a formula
that will calculate elapsed time like:

In A4 (if A2 is not blank than - A1, if it is blank than A3-A1)

I have tried many different examples that I have found on here, but
with no luck. Thank You!!
