Are they date columns? If so (and they *should* be), simply subtract.
As they are numbers, simply subtract, and do some math, you know, like dividing through the number of seconds in a minute, in an hour, etc.

I don't know where you had the idea UTC has a format that does something magical with the year 1970. UTC is a time *zone*, not a format.
Formerly known as Greenwich time.
