Would the '1 day' result know it was 24 hours or be the new 23/24/25
hour version of '1 day'?
If it was the new version, could you get the original values back?
i.e. what would be the result of
select
('2005-10-29 13:22:00-04'::timestamptz +
('2005-10-30 13:22:00-05'::timestamptz -
'2005-10-29 13:22:00-04'::timestamptz)) at time zone 'EST';
