JDBC timestamps with timezones

От

In reading about how Timestamps are stored in Postgresql 7.1 (they are
stored in GMT based on the TZ in effect on the server running the backend),
I was wondering how this impacts JDBC.

We want to be able to retrieve timestamps from the database and then show
them to invididual users based on their specified timezone which we know in
advance.  With Java, I can take a Date/Calendar and get the current time
using a specified TimeZone object.  Does the JDBC then know to always
retrieve the timestamp and keep it internally as GMT, too so that all the
time zone stuff will work?

Thanks,
David

You shouldn't have any problems with the 7.1 drivers doing what you
need.  The 7.1 jdbc driver should correctly handle timezones.  The 7.0
drivers didn't work correctly if the client timezone and server
timezones were different.

Since 7.1 is still in beta, please test it out and report any bugs you find.

thanks,
--Barry
