Sounds like we're on the same page then.

Hour field of the timestamp, or hour field of interval? There a world of
difference.
As long as we're willing to live with the understanding that +1day 1 hour may
produce a slightly different result than + 25 hours, I don't see the problem.
Currently I can add +900 hours if I like, postgreSQL will support it.
