python获取网络时间和本地时间

今天我们来看一下如何用python获取网络时间和本地时间，直接上代码吧，代码中都有注释。

python获取网络时间

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("rn")             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获取本地时间

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])
