28 * Persist {@link ZonedDateTime} via Hibernate. This type is
29 * mostly compatible with org.joda.time.contrib.hibernate.PersistentDateTime however
30 * you should note that JodaTime's org.joda.time.DateTime has only millisecond precision,
31 * whilst JSR 310 offers nanosecond precision. When interpreting nanosecond values, Joda time will
32 * round down to the nearest millisecond. The type is stored using the timezone as configured
33 * using Hibernate's configuration property 'hibernate.jdbc.time_zone' and presented in the
34 * JVM using the JVM's default zone. You can optionally override or use as an alternative to this property the
35 * parameter 'databaseZone' on this type.
36 *
37 * Alternatively provide the 'javaZone' can be used to similarly configure the zone of the
38 * value on return from the database.
