What is the data type of the event_tim column? Do I need to find the time difference between row 1 and row 2 in order to get the time a channel was watched? So etv would be watched for 8 seconds and then Gemini for 9 seconds then back to etv, but there is on way of knowing when the last row ended in the data you supplied. What would I do with the last row?
