  /**
   * Persist {@link Interval} via Hibernate. The interval type is intended to be compatible with
   * org.joda.time.contrib.hibernate.PersistentInterval and stores beginning and end values.
   * The types are stored using the timezone as configured 
   * using Hibernate's configuration property 'hibernate.jdbc.time_zone' and presented in the
   * JVM using the JVM's default zone. You can optionally override or use as an alternative to this property the 
   * parameter 'databaseZone' on this type.
   *
   * Alternatively provide the 'javaZone' can be used to similarly configure the zone of the
   * value on return from the database.
