说明：  门锁系统是通过服务器的时钟来转换得到宾客流水号的，因为时间不停的往后推移，所以换算得到的识别号将会越来越大。具体算法：以2000-01-01 00:00:00为基准，此时识别号的值为0，时间过1秒则识别号的值加1。也就是说，识别号的值是当前时间与基准时间所相差的秒的总数。
(Lock system is to convert the clock through the server serial number by guests, as time goes on constantly in the back, so the conversion will be the identification number is growing. The algorithm: The 2000-01-01 00:00:00 as a benchmark, then ID is 0, the time over 1 second, the identification number of the value plus 1. In other words, identification number and the reference value is the current time difference between the time the total number of seconds.)
