Need to control the hourcycle for DateIntervalFormat

Description

Currently, there are no way to force the DateIntervalFormat to handle h11, h12, h23 and h24.
The use of "skeleton" does not guarantee DateIntervalFormat will always return pattern for K or k
We need a way to force the DateIntervalFormat to handle K or k
