python实现定时同步本机与北京时间的方法

本文实例讲述了python实现定时同步本机与北京时间的方法。分享给大家供大家参考。具体如下：

这段python代码首先从www.beijing-time.org上获取标准的北京时间，然后同步获取的北京时间到本地

# -*- coding: utf-8 -*-
import time,httplib
import threading
def getBeijinTime():
  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:
      result = response.read()
      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:
    return None
def syncLocalTime():
  """
  同步本地时间
  """
  beijinTime = getBeijinTime()
  if beijinTime is None:
    timer = threading.Timer(30.0, syncLocalTime)
    timer.start()
  else:
    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
if __name__=='__main__':
 while True:
   syncLocalTime()
   time.sleep(30)

希望本文所述对大家的Python程序设计有所帮助。
