compareTo method

int compareTo(Duration other)

Compares this Duration to other, returning zero if the values are equal.

Returns a negative integer if this Duration is shorter than other, or a positive integer if it is longer.

A negative Duration is always considered shorter than a positive one.

It is always the case that duration1.compareTo(duration2) < 0 iff (someDate + duration1).compareTo(someDate + duration2) < 0.
