> Given two timestamps that each have time zones this function should return an interval from the first timestamp to the second timestamp according to the following rules (postgres rules):
> * 1 day is 24 physical hours (which may not exactly equal 1 calendar day).
> * Intervals returned will never contain a months/years field
> Examples:
> interval_between('2021-03-14 00:00:00 America/Denver', '2021-03-15 00:00:00 America/Denver') => { "hours": 23 }
> interval_between('2021-03-14 00:00:00 UTC', '2021-03-15 00:00:00 UTC') => { "days": 1}
> interval_between('2021-03-14 00:00:00 UTC', '2020-03-14 00:00:00 UTC') => { "days": 365}
> If the first timestamp is larger than the second timestamp then the interval will be negative.
