This is closely aligned with tables B-4 and B-5 of the JDBC 4.2 specification.
Note that `ZonedDateTime`, `Instant` and
`OffsetTime / TIME [ WITHOUT TIMEZONE ]` are not supported. Also note
`OffsetTime / TIME [ WITHOUT TIME ZONE ]` are not supported. Also note
that all `OffsetDateTime` will instances will have be in UTC (have offset 0).
This is because the backend stores them as UTC.
