I have a column for Delivery Time (Type = Time) - this is a specified time that delivery should take place. I have an additional column called Actual Time (Type = ChangeTimestamp) - This is the actual time the delivery took place.
How can I calculate the difference between the 2 times?
Delivery Time = 10:49:28 AM Actual Time = 23/03/2018 12:21
Thanks in advance
