Calculating hour differential over multiple days
I'm trying to calculate the number of hours elapsed between when a given event occurred and the current time. Both are formatted as "DD MMM YYYY HH:MM: SS". Basically, if the event occurred at 01 Jan 2019 12:30:00, and the current date is 03 Jan 2019 12:00:00, I would like the output to be 47:30:00 Thanks!
