Sum the time based on criteria multiple in and out

Solution 1:

If you simply take all of the Out times and subtract all if the In times, you will get the total time spent.

Caveat: There must be a matching Out Time for every In time. You might want to create a warning (possibly a CFR) to show when there isn't. The time format in E3:F3 should also be like [hh]:mm:ss so that >24hrs is clearly visible.

Put the following formula into E3 and fill right.

=SUMIFS($A:$A, INDEX($B:$C, , MATCH(E$2, $B$1:$C$1, 0)), "out")-
 SUMIFS($A:$A, INDEX($B:$C, , MATCH(E$2, $B$1:$C$1, 0)), "in")

I've made the formula truly dynamic so you won't have to change anything when dragging right.
