Re: JDBC Driver and timezones

Hi,

actually, your application server is not using the system's default
timezone, see the configuration of your server.

I actually have filed this in the past as either bug or enhancement.
Basically the problem lies within the PGSQL JDBC driver, which will use
the application server's timezone setting when interpreting the data in
the timezone enabled table attributes.

In order to overcome this problem, I have adjusted a db layer that we are
using in the OSS VerA.Web project so that it will use proxies for the most
relevant objects (resultset and so on) that then will just drop the
timezone information in the data received from the database, so that when
instantiating the datetime object in the application server, it will
automatically take over the configured timezone. That way, you will
experience no timeshift, whatsoever.

See

for more information.

Regards,

Carsten
