Oracle/JDBC Time Discrepancy

Question

I have an Oracle procedure that rebuilds the index and a java application that calls the procedure. I don�t pass any timestamp at all, I just tell it to start and how long (approx) to run and then post the results in the GUI. When I run the procedure in the Oracle SQL Developer the start time is correct, however, when I run the same procedure though my Java Swing app the time stamp is 4 hours ahead of the current time. This confuses the users and is driving me nuts! The DB and the application are on one machine so there shouldnt be a time discrepancy. Any advice on how get Oracle to give Java the right time?
For a test I ran the following code:
    public void retrieveTimeZone()
         String query = "select to_char(current_timestamp, 'dd Mon yyyy hh24:mi:ss') from dual";
        CallableStatement cs = null;
        ResultSet rs = null ;
        logMonitorList = new ArrayList();//reset list
         TimeZone tZone = TimeZone.getDefault();
        System.out.println("Java Date=" +new Date().toString());
        System.out.println("tZone=" +tZone.toString());
      try
             logger.logEvent(className, "retrieveTimeZone", "Query=" +query);
              cs = getDBConnection().prepareCall(query);
              rs = cs.executeQuery();
              while(rs.next())
                   System.out.println("Oracle through Swing app time="+rs.getString(1));
        catch (SQLException e)
             logger.logEvent(className, "retrieveLogMonitor", e.toString());
        finally
             //close connections etc�
    }The output is:
Java Date=Thu Jun 12 *17:18:57* EDT 2008
tZone=sun.util.calendar.ZoneInfo[id="America/New_York",offset=-18000000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/New_York,offset=-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]]
Oracle through Swing app time=12 Jun 2008 *21:18:57*
Thanks!

Thanks for your help, it got me going in the right direction. It appears that since I'm using an older version of the JDBC driver (the app I�m working on is about 6 years old), there is a discrepancy in time zones. This issue was fixed in version 11 of the JDBC driver. Here�s the code that fixed it:
TimeZone tZone = TimeZone.getDefault();
OracleConnection oConn = null;
try
oConn = getOracleDBConnection();
               oConn.setSessionTimeZone(tZone.getID());
               stmt = oConn.createStatement();
                                               rs = stmt.executeQuery(query);
          catch( SQLException e )
               throw new SQLException( "Error running XYZ procedure : " + e.toString());                          }
          catch ( DAOException e )
               throw new DAOException( "Error running XYZ procedure : " + e.toString());               }         
          finally
               if ( rs != null ){rs.close();}
               if ( cs != null ){cs.close();}
               if ( stmt != null ) {stmt.close();}
               if(dao != null){dao.close();}
