Add support to pass-thru `TemporalAccessor` auditing values

[xenoterracide]

This is incorrect, it would seem that java.time.Instant is also supported, sorry if this belongs in the commons repo. Note, I was trying to use OffsetDateTime for this.

businessDivisionId=a

]; Supported types are [org.joda.time.DateTime, org.joda.time.LocalDateTime, java.util.Date, java.lang.Long, long]

see this ticket, but especially this comment.

Most databases support "with timezone", javascript Date only seems to support offset, and so it is useful in cases to be able to communicate that and store it in the database.

To clarify:

• You prefer to use OffsetDateTime for auditing timestamps, which are currently not supported by Spring Data.
• Instant does work although not official supported.

Can you please confirm this interpretation of the issue is correct?

Side note: the suppport for OffsetDateTime of some database JDBC drivers is quite limited in that they just drop the offset.

hmm... yes that is the correct interpretation. Interesting to learn that they drop, is that true if the underlying type is some kind of "timestamp with timezone"? Longterm the goal is both consistency, and dealing with silly people. In non auditables

json (Date only supports offset) -> server -> timestamp with offset stored

because for some reason someone wants localtime stored ,and we're also using the above

audit -> timestamp with offset stored (usually means a timestamp with timezone type)

another argument would be consistency, as doesn't hibernate just work with offsetdatetime? (sorry, it's now been a minute again)

TIMESTAMP_WITH_TIMEZONE is an official column type defined by SQL standards, but support is indeed hit and miss even among popular and modern relational databases. PostgreSQL supports it out of the box and recommends its use, but other database systems don't (e.g. MariaDB).

@schauder May I ask what you mean by OffsetDateTime is not/sketchily supported by Spring Data? (I'm assuming you are referring to OffsetDateTime support in general, not just the auditing functionality). To what extent is this still true since version 2.2? I'm going by baeldung on jpa 2.2, but I think you might be referring to problems occurring 'under the hood'.

[schauder]

I was referring to the JDBC drivers. I clarified my comment above. If I'm not mistaken some databases simply ignored the offset.

personally, sounds like a good note to put in docs, but a bug in those drivers? personal opinion
