/**
* 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.
