> Priority: Major

> {code:java}
> * The operator `OVERLAPS` determines whether or not two chronological
> periods overlap in time. A
> * chronological period is specified by a pair of datetimes (starting and
> ending).
> *
> * If the length of the period is greater than 0, then the period consists of
> all points of time
> * greater than or equal to the lower endpoint, and less than the upper
> endpoint,
> * a.k.a [lower, upper).
> *
> * If the length of the period is equal to 0, then the period consists of a
> single point in time,
> * the lower endpoint, a.k.a [lower, lower].
> *
> * Two periods overlap if they have at least one point in common.
