用于更改系统日期和时间的Python模块
用于更改系统日期和时间的Python模块
提问于 2012-08-23 04:58:22
如何在Python中更改系统日期、时间和时区？有没有什么模块可以用来解决这个问题？
- 我不想执行任何系统命令
- 我想要一个通用的解决方案，它应该在Unix和
- 上都能工作。

_win_set_time(time_tuple)我没有windows机器，所以我没有在windows上测试它...但你明白我的意思。

我不得不稍微修改一下win32版本的tMC的答案：
def _win_set_time(time_tuple):
import win32api
dayOfWeek = datetime(*time_tuple).isocalendar()[2]
t = time_tuple[:2] + (dayOfWeek,) + time_tuple[2:]
win32api.SetSystemTime(*t)例如：当我使用它来根据旧的时间服务器(时间协议，RFC868)设置时间时，我是这样做的：
data = s.recv(4)
remote_time = (ord(data[0])<<24) + (ord(data[1])<<16) + (ord(data[2])<<8) + ord(data[3])
remote_time -= 2208988800
_win_set_time(time.gmtime(remote_time)[0:6] + (0,))Stack Overflow用户

tMC的回答似乎很好。然而，它并不适合我。我发现它需要一些更新，对于Linux和Windows + python 3都是如此。
import sys
from _datetime import datetime
time_tuple = (2012, # Year
9, # Month
6, # Day
0, # Hour
38, # Minute
0, # Second
0, # Millisecond
)
def _win_set_time(time_tuple):
import win32api
dayOfWeek = datetime(*time_tuple).isocalendar()[2]
t = time_tuple[:2] + (dayOfWeek,) + time_tuple[2:]
win32api.SetSystemTime(*t)
def _linux_set_time(time_tuple):
import subprocess
import shlex
time_string = datetime(*time_tuple).isoformat()
subprocess.call(shlex.split("timedatectl set-ntp false")) # May be necessary
subprocess.call(shlex.split("sudo date -s '%s'" % time_string))
subprocess.call(shlex.split("sudo hwclock -w"))
if sys.platform == 'linux2' or sys.platform == 'linux':
_linux_set_time(time_tuple)
elif sys.platform == 'win32':
_win_set_time(time_tuple)对于Linux，请阅读以下答案：Set the hardware clock in Python?
