问题描述

限时送ChatGPT账号..

Python 在 Windows 下运行时，如果在 Python 实例的生命周期内更改时区，则 time.localtime 不会报告正确的时间.在 Linux 下，总是可以运行 time.tzset 来缓解这样的问题，但在 Windows 中似乎没有等价物.

When Python is running under Windows, time.localtime does not report the correct time if the timezone is changed during the life time of the Python instance. Under Linux, time.tzset can always been run to alleviate problems like this, but there appears to be no equivalent in Windows.

有没有办法解决这个问题而不做一些荒谬的事情，比如，哦，我不知道......

Is there a way to fix this without doing something absurd like, oh, I don't know...

#!/bin/env python
real_localtime = eval(subprocess.Popen(
    ["python","-c", "import time;repr(time.localtime())"],
    stdout=subprocess.PIPE)municate()[0])

推荐答案

更合理的解决方案是使用 Kernel32 的 GetLocalTime 与 pywin32 或 ctypes.任何时区更改都会立即反映出来.

A more rational solution is to use Kernel32's GetLocalTime with pywin32 or ctypes. Any time zone changes are reflected immediately.

import ctypes
class SYSTEMTIME(ctypes.Structure):
    _fields_ = [
        ('wYear', ctypes.c_int16),
        ('wMonth', ctypes.c_int16),
        ('wDayOfWeek', ctypes.c_int16),
        ('wDay', ctypes.c_int16),
        ('wHour', ctypes.c_int16),
        ('wMinute', ctypes.c_int16),
        ('wSecond', ctypes.c_int16),
        ('wMilliseconds', ctypes.c_int16)]

SystemTime = SYSTEMTIME()
lpSystemTime = ctypes.pointer(SystemTime)
ctypes.windll.kernel32.GetLocalTime(lpSystemTime)
print SystemTime.wHour, SystemTime.wMinute
