Description : MS Excel Help: Calculate Amount of Time?
Last Answer : If your timestamps are in columns A and B, I'd imagine this would do the trick: =B1-A1 and then make sure to set the cell format to time, showing the difference in minutes and seconds. Just tested with this: timestamp A ... = custom: dd/mm/yyyy hh:mm:ss) =B-A: 0:29:57 (cell format = custom: h:mm:ss)
