You seem to be asking for the behavior of the second variant. Use at your own risk. If I want the number of hours I would need to extract the number of days, multiply it by 24, and then add the extract of hours.

Multiplication and division of INTERVALS is under development and u at this time It is suggested that you avoid it until implementation is complete or you may get unexpected no. Readers should make note of this. How does the evaluation work. Use at your own risk.Browse other questions tagged or. In reply to your comment.
