Use this to calculate the difference between two time fields in hours, minutes, or seconds.

– for hours use ‘h’ instead of ‘m’
– for seconds use ‘s’ instead of ‘m’ – Note: Since time fields capture only hours and minutes, this difference will always be rounded to the nearest 60 sec.

Fields used in calculation

secondtime point (time field)
