27 * Persist {@link Instant} via Hibernate using a JDBC Timestamp datatype with a reference date. - note that sub-second values will not
28 * be retained.
29 *
30 * The type is stored using the timezone as configured
31 * using Hibernate's configuration property 'hibernate.jdbc.time_zone' and presented in the
32 * JVM using the JVM's default zone. You can optionally override or use as an alternative to this property the
33 * parameter 'databaseZone' on this type.
34 *
35 * Alternatively provide the 'javaZone' can be used to similarly configure the zone of the
36 * value on return from the database.
