Team,
It took me some time to figure out how to display duration. I have 3 columns " Date Created " " Time Completed " & " Duration " I have attached an image for refference.
Formula - copy this into the first row of that column. Remember to either rename your columns or change the formula. Cheers!!
=INT([Time Completed]@row - [Date Created]@row) + "d " +
INT(MOD(([Time Completed]@row - [Date Created]@row) * 24, 24)) + "h " +
INT(MOD(([Time Completed]@row - [Date Created]@row) * 1440, 60)) + "m"
