Error selecting dates around DST

Question

I am having a problem selecting dates from a database at the office. I seem to be unable to select anything on the EDT switchover. I have tried various JDBC versions and it seems to be always wrong. below is my output followed by the code.
I would expect to see this:
2012-03-11 02:24:00.0
2012-03-11 03:24:00.0
What I get
ojdbc14-10.1.0.2.0.jar
2012-03-11 01:24:00.0
2012-03-11 03:24:00.0
ojdbc6_g-11.2.0.2.0.jar
2012-03-11 03:24:00.0
2012-03-11 03:24:00.0
ojdbc6_g-11.2.0.3.jar
2012-03-11 03:24:00.0
2012-03-11 03:24:00.0
import java.sql.*; public class JDBCTest {   public  static void main(String[] args) throws SQLException {     DriverManager.registerDriver(new oracle.jdbc.OracleDriver());     ResultSet bat = DriverManager.       getConnection("--JDBCURL--", "username", "password").       prepareCall("select to_date('3/11/2012 02:24:00','mm/dd/yyyy HH:MI:SS') theDate from dual").       executeQuery();     bat.next();     System.out.println(bat.getTimestamp("theDate"));   ResultSet man = DriverManager.       getConnection("--JDBCURL-", "username", "password").       prepareCall("select to_date('3/11/2012 03:24:00','mm/dd/yyyy HH:MI:SS') theDate from dual").       executeQuery();     man.next();     System.out.println(man.getTimestamp("theDate"));   } }
Any ideas on what could be going wrong? What kind of stuff should I be looking at in the DB environment? Is this a potential bug I should file somewhere? Thanks

Your expectations are wrong. There is no 2am thru 2:59:59 am during DST. At 2am the clock moves to 3am so 02:24:00 does not exist.
I get the same results for all of those jar files (including 1.4) except I am not using the _g versions.

2012-03-11 03:00:00.0 -- value used was for 02:00:00
