Java: MySQL DATETIME conversion errors?

I do the following in my java application:

Statement s = myConnection.createStatement();
ResultSet rs = s.executeQuery("SELECT startTime FROM MyTable WHERE
_rowid=1");
if (rs.next())
{
java.sql.Timestamp stamp = (java.sql.Timestamp)rs.getObject(1);
String startTime = stamp.toString();
}

I get the following value in startTime: "2006-03-02 12:00:00.0"
But in the database is the following value stored: "2006-02-30 12:00:00.0"

I am running MySQL 4.1.12 on RedHat Linux ES 4.0 EMT64.
I run my java application on Windows 2000 with java 1.5.0_03-b07 and
mysql-connector-java-3.1.12. I have also tried
mysql-connector-java-5.0.0-beta, same problem.

Any idea?
Thank you.

No such date as Feb 30th

It is assuming you mean 2 days after Feb 28th.

Yes. This was reported as a bug
(http://bugs.mysql.com/bug.php?id=16147) and was closed, claiming it is
intentional behavior.

In 5.0, if you try to put in an invalid date, it issues a warning or an
error by default.

SELECT DATE('2006-02-30');
Error 1292 Truncated incorrect datetime value: '2006-02-30'

SET GLOBAL SQL_MODE='ALLOW_INVALID_DATES';
SELECT DATE('2006-02-30');
2006-02-30

In 4.1 and prior releases, MySQL allows invalid dates; day must be
0..31, and month must be 0..12.
