Mark Struberg resolved OPENJPA-2178.
------------------------------------
Resolution: Fixed
> PostgresDictionary
> -------------------
>
> Key: OPENJPA-2178
> URL: https://issues.apache.org/jira/browse/OPENJPA-2178
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Mark Struberg
> Assignee: Mark Struberg
> Fix For: 2.3.0
>
>
> We hit a problem that OpenJPA always rounds to the nearest 10ms for
> PostgreSQL. We found the following old issue in which a workaround got
> outlined in OPENJPA-433
> But still the question remains: PostgreSQL is perfectly fine to store
> milliseconds, so why does the PostgresDictionary line 146 sets:
> > datePrecision = CENTI;
> ?
> The generated TIMESTAMP type in PostgreSQL should even be able to store
> microseconds! [1]
> And that seems to be the case since quite some time now (1999) [2].
> I'm really tempted to set this to MICRO; Anyone against it?
