How Do I Calculate the Time Difference Between 2 Variables? Example: You have 2 variables (Start_Time (V3) and Stop_Time (V4)) The Start_Time & Stop_Time variables must be defined as Numeric with 2 decimal places. When entering data into the Start_Time & Stop_Time variables use a decimal between the hour and minutes. Example: 10:30 would be entered as 10.30 10:59 would be entered as 10.59 The Calculated time difference variable (V5) can be divided by 60 for minutes or by 3600 for hours. Example: Time_Diff (V5) would be calculated as @TIMEDIFF[V3,V4] to return seconds @TIMEDIFF[V3,V4]/60 to return minutes @TIMEDIFF[V3,V4]/3600 to return hours The variable (V5) that calculates the time difference should also have 2 decimal places.
