使用Python设置系统时间(给系统校时)

#电脑时间用了一段时间后,系统时间不准了,想更新一下

#在windows里面,更新系统时间,时常失败,而且速度很忙.

#在网上拷贝的代码,发现很好用,比windows自带的实现要快.

import socket
import struct
import time
import win32api

TimeServer = '210.72.145.44' #国家授时中心ip
Port = 123

def getTime():
TIME_1970 = 2208988800L
client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
data = '\x1b' + 47 * '\0'
client.sendto(data, (TimeServer, Port))
data, address = client.recvfrom(1024)
data_result = struct.unpack('!12I', data)[10]
data_result -= TIME_1970
return data_result

def setSystemTime():
tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, tm_isdst = time.gmtime(getTime())
win32api.SetSystemTime(tm_year, tm_mon, tm_wday, tm_mday, tm_hour, tm_min, tm_sec, 0)
print "Set System OK!"

if __name__ == '__main__':
setSystemTime()
print "%d-%d-%d %d:%d:%d" % time.localtime(getTime())[:6]

速度很快的,只要双击一下Py文件就可以了
