I'm inclined to think that disallowing AM/PM for intervals was a mistake
--- if we allow both HH and HH24 (which we do) then the various flavors
of AM/PM seem reasonable to allow as well.
Bruce, did you have a specific rationale for that?
I notice the code now specifically forces HH to be treated as HH24 in
the interval case, which was not so before 8.1; we would need to revert
that change as well to continue supporting TIME cases reasonably.
