+ * DateTime type saving additional timezone information.
+ *
+ * Caution: Databases are not necessarily experts at storing timezone related
+ * data of dates. First, of all the supported vendors only PostgreSQL and Oracle
+ * support storing Timezone data. But those two don't save the actual timezone
+ * attached to a DateTime instance (for example "Europe/Berlin" or "America/Montreal")
+ * but the current offset of them related to UTC. That means depending on daylight saving times
+ * or not you may get different offsets.
+ *
+ * This datatype makes only sense to use, if your application works with an offset, not
+ * with an actual timezone that uses transitions. Otherwise your DateTime instance
+ * attached with a timezone such as Europe/Berlin gets saved into the database with
+ * the offset and re-created from persistence with only the offset, not the original timezone
+ * attached.
