python脚本设置系统时间的两种方法
本文为大家分享了两种python脚本设置系统时间的方法，供大家参考，具体内容如下
第一种方法，使用Python设置系统时间，即给系统校时
#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.
#-*- coding:utf-8 -*-
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
第二种方法，python第三方库推荐，通过ntplib在windows上同步时间
很多时候我们有通过程序脚本同步校正北京时间的需求。
在linux上同步时间比较方便，安装个ntpdate软件就行了。
但是在windows的要同步时间比较麻烦。
这时想到的就是从网络获取一个准确的时间，然后调用dos命令修改时间。
从哪里获取呢？当然是国家授时中心。
授时中心的网址是 cn.pool.ntp.org(注意，流传甚广的210.72.145.44这个ip已经失效了，直接用域名。)
不过从授时中心获取的时间需要ntp协议解析。
ntplib就是干这事的。
另外值得一提的是在dos修改日期时间要通过2个命令实现，date命令修改日期，time命令修改时间。
安装ntplib:
easy_install ntplib或pip install ntplib
下面上代码。
import os
import time
import ntplib
c = ntplib.NTPClient()
response = c.request('pool.ntp.org')
ts = response.tx_time
_date = time.strftime('%Y-%m-%d',time.localtime(ts))
_time = time.strftime('%X',time.localtime(ts))
os.system('date {} && time {}'.format(_date,_time)) 以上就是本文的全部内容，两种python脚本设置系统时间的方法，大家学会了吗？

Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
