Joda Time get Duration between two Instants

Question

I have two Instant objects and would like to get a Duration indicating how much time is between them, however Instant.minus only accepts either a ReadableDuration or a long for the amount of time to change by, and doesn't seem to have any method for subtracting two instants to get the difference between them.

Other answers that I found seem to suggest converting both instants to milliseconds and doing the math myself, but I would prefer something that retains type safety and doesn't require re-implementing end - start logic.

How can I get a Duration from two Instants?

Answer 1

Duration has a constructor which takes two ReadableInstant objects for the start and end of the Duration.
