结果集的java日期相关方法不起作用

我正在使用jdk-1.6， os-Redhat5，司机-12级。jar（jar和jdk库）数据库甲骨文10i

代码：-

  public Timestamp getCurrentTimeStamp(Connection connection) throws SQLException {
        Timestamp timeStamp = null;
        try {
            PreparedStatement ps = connection.prepareStatement(" SELECT CURRENT_TIMESTAMP FROM DUAL");
            ResultSet rs = ps.executeQuery();
            if (rs.next()) {
                timeStamp = rs.getTimestamp("CURRENT_TIMESTAMP");
            }

        } catch(Exception e){}
        return timeStamp;
    }

在某些系统中，它工作正常，但在服务器上，它只抛出以下异常

只有resultset的时间相关函数不起作用。。。。。。。。（resultset.getTimestamp（），resultset。getDate（））。但是结果集。getString（）工作正常

在java论坛中，我得到了答案，这是因为JRE时区设置与oracle return时区设置不同。。。这是正确的还是错误的。。。。。或者我该如何解决这个问题。。。。。。。。。。。。请帮帮我
