Hi,
Just like to point out, formula suggested in Post # 2 results in Real Time value (Real Number), whereas, formula from Post # 3 results in Text (meaning you won't be able to do further comparison/math).
For those who might be interested, if there were not always that exact format (leading zeros for single digit minutes and/or seconds), then this formula would work (also works if the format is exact also, of course)...If they are all in EXACTLY that format
