Marios Trivyzas fd1bb4a33a SQL: Fix issue with mins & hours for DATEDIFF (#49252)
Previously, DATEDIFF for minutes and hours was doing a
rounding calculation using all the time fields (secs, msecs/micros/nanos).
Instead it should first truncate the 2 dates to the respective field (mins or hours)
zeroing out all the more detailed time fields and then make the subtraction.
