Here is a really simple test:

public class DateTest {

public static void main(String[] args) throws Exception {
Class.forName("org.postgresql.Driver");
Connection connection =
DriverManager.getConnection("jdbc:postgresql://host/db");
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery("select id, effective from
date_test");
while(rs.next() ) {
Date effective = rs.getDate("effective");
int id = rs.getInt("id");
System.out.println("id="+id+", effective=" +
effective.getTime());
}
connection.close();
}
}

Schema Stuff:

CREATE TABLE date_test
(
effective date,
id int2
)

INSERT INTO date_test VALUES ('2005-07-26', 1);
INSERT INTO date_test VALUES ('2005-07-26', 2);
INSERT INTO date_test VALUES ('2005-07-26', 3);

The output results:

/usr/java14/bin/java -cp "/usr/insight/postgresql.jar:." DateTest

id=1, effective=1122350400000 <--- correct
id=2, effective=1122354000000 <--- +1 hour
id=3, effective=1122354000000 <--- all same from here out

It's quite weird that it's different on the first row, otherwise I'd say
it was a local JVM timezone issue.

Do you have some test code we can try? Without knowing what the
underlying column's type is or which ResultSet accessor you're using
it's just guesswork.
