 *  @brief 获取此时MCU的时间
 *  @param NULL
 *  @return 没有返回值
 */
    void getNowTime();

/*!
 *  @brief 更新MCU的时间
 *  @param hour,minute,second
 *  @return 没有返回值
 */

 *  @brief 更新MCU的时间
 *  @param hour,minute,second
 *  @return 没有返回值
 */

/*!
 *  @brief 清空MCU时刻表，时刻表是用来记录红绿灯在不同时间段红绿黄三个灯持续亮的时间
 *  @param NULL
 *  @return 没有返回值
