[Pljava-dev] date handling...

George,
This is probably a bug. PL/Java has to do some adjustements in order to
get java.sql.Date to work correctly but something is obviously wrong.

A java.sql.Date in java extends from java.util.Date. It's internal
representation is in milliseconds since midnight 1970-01-01. If the
timezone used by your server differs from the one that the JVM uses,
"midnight" may be translated some time in the evening the day before.

Can you please print the timezone that your server uses and the timezone
that the JVM thinks it has, i.e. TimeZone.getDefault() and see if
there's a differenence?

Regards,
Thomas Hallgren
