Hi @rob_marshall I see the method that you used to record time of calculation but I have my doubts here. Lets say you wrote a formula in a line item at 12:00:00 (ID:-1). Now you want to record the time of calculation, so you remove this formula at 12:01:00 (ID:-2), pasted it back at 12:01:20 (ID:-3). As I understand the history timestamps, ID:-3 shows the time when you pasted the formula but not the calculation time of that formula. (I may be wrong here) As this method of calculating time includes human steps (removing and pasting), what if you pasted the formula 1 sec late. Will that second not be counted between two timestamps? The internet may also play a role here. For example the changes were not recorded right away due to low internet speed and it took some time to register those changes, which I think, is also counted between timestamps. I may be completely wrong here about the concept of history timestamps. Please clarify these doubts. Thanks! -Shubham
