    Hi RAKS,

    Assuming that there are no issues with the rows in your dataset, this can be accomplished through a prepare recipe. Please see below for more details.

    Step 1: Concatenate columns

    This will output a string with the format of yyyyMMddHHmmss. You will use this in the next step.

    Step 2: Format the string into a proper timestamp

    This will output a new column, timestamp_start_formatted in a proper date format.

    Do the above for your start time and stop time before continuing to calculate the time between columns.

    Step 3: Calculate the time between two columns.

    As you can see, this step will calculate the time in minutes from column timestamp_start_formatted until column timestamp_stop_formatted.

    You can change the column names to whatever your column's names are/want to be.

    A sample output from the dataset that you provided:

    Hope this helps!
