Python gets network time and local time

Today we will take a look at how to use python to get the network time and local time. Let’s go directly to the code. There are comments in the code.

python gets network time

获取网络时间
 def getBeijinTime():
     """
 　　 获取北京时间
     """
     try:
         conn = httplib.HTTPConnection("www.beijing-time.org")
         conn.request("GET", "/time.asp")
         response = conn.getresponse()
         print response.status, response.reason
         if response.status == 200:
             #解析响应的消息
             result = response.read()
             logging.debug(result)
             data = result.split("\r\n")
             year = data[1][len("nyear")+1 : len(data[1])-1]
             month = data[2][len("nmonth")+1 : len(data[2])-1]
             day = data[3][len("nday")+1 : len(data[3])-1]
             #wday = data[4][len("nwday")+1 : len(data[4])-1]
             hrs = data[5][len("nhrs")+1 : len(data[5])-1]
             minute = data[6][len("nmin")+1 : len(data[6])-1]
             sec = data[7][len("nsec")+1 : len(data[7])-1]
               
             beijinTimeStr = "%s/%s/%s %s:%s:%s" % (year, month, day, hrs, minute, sec)
             beijinTime = time.strptime(beijinTimeStr, "%Y/%m/%d %X")
             return beijinTime
     except:
         logging.exception("getBeijinTime except")
         return None

python gets local time

同步本地系统时间
 def syncLocalTime():
     """
     同步本地时间
     """
     logging.info("current local time is: %d-%d-%d %d:%d:%d" % time.localtime()[:6])
       
     beijinTime = getBeijinTime()
     if beijinTime is None:
         logging.info("get beijinTime is None, will try again in 30 seconds...")
         timer = threading.Timer(30.0, syncLocalTime)
         timer.start();
     else:
         logging.info("get beijinTime is: %d-%d-%d %d:%d:%d" % beijinTime[:6])
               
         tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec = beijinTime[:6]
         import os
         os.system("date %d-%d-%d" % (tm_year, tm_mon, tm_mday))     #设置日期
         os.system("time %d:%d:%d.0" % (tm_hour, tm_min, tm_sec))    #设置时间
         logging.info("syncLocalTime complete, current local time: %d-%d-%d %d:%d:%d \n" %time.localtime()[:6])
