阿里的mq的demo中怎么发送不了定时消息，配置了还是当时就发送

public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("producer/producer.xml");
HttpMQProducerServiceImpl producer = context.getBean(HttpMQProducerServiceImpl.class);

    // 发送定时消息: producer.send("msg", "tag", "key", startDeliverTime);
    Long timeStamp=null;
    try {
        timeStamp =new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2017-02-16 10:26:00").getTime();
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
        if (producer.sendMessage("nihao","meinu","什么",timeStamp)) {
            System.out.println("send message success");
        } else {
            System.out.println("send message failed");
        }

    //context.close();
}

检查你的时间戳，要考虑时区。
