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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

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获取本地时间

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

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])
