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?

How do you create multi-dimensional arrays using NumPy?How do you create multi-dimensional arrays using NumPy?Apr 29, 2025 am 12:27 AM

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
