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。
