The lower the number the more severe it is.

Short Description
JDBC-Driver produces wrong output.

Long Description

I recently downloaded the last snapshot of PostgreSQL and also the newest JDBC-Driver for it. I played a bit around with it and it seems to produce some really weird output on datetimes and timestamps. I added a table "test" into the database, containing two columns "test1" and "test2". "test1" is a timestamp, "test2" a datetime. Then I entered the following date into each of the columns: 15.10.1978 20:47:56 CET. After this I ran a small test program (see the attached source code). This produced the following output:

|1981-11-15 20:00:56.0|1981-11-15 20:00:56.0

As you can see, the dates are different from what I entered into the database. This error did not occur using the 6.4 PostgreSQL and belonging driver. Do I do something wrong ?

Sample Code
Hashtable defaultProperties = new Hashtable();
defaultProperties.put(JDBCResource.HOSTNAME, "frodo");
defaultProperties.put(JDBCResource.PORT, "5432");
defaultProperties.put(JDBCResource.USERNAME, "jan");
defaultProperties.put(JDBCResource.PASSWORD, "");
defaultProperties.put(JDBCResource.DATABASE, "testdb");

Connection connection = DriverManager.getConnection(...)
Statement statement = connection.createStatement();

ResultSet rs = statement.executeQuery("SELECT * FROM test");
while ( {
   int cols = rs.getMetaData().getColumnCount();
   for (int i=1; i<=cols; i++) {
       System.out.print("|" + rs.getObject(i));
