问题描述



我只在Windows上试过这个:


在Python 2.4中os.path.getmtime返回当地时间,

在Python 2.5中它似乎返回GMT:


import os,time

print ctime.time(os.path.getmtime(foo))


在时区上与Python 2.4和Python 2.5不同。


现在,两个stat调用的实现在Windows上有所不同

两个版本之间。


我实际上更喜欢新的行为,因为我相信

报告文件的时间不应该依赖于时区或其他

本地设置,但旧的行为也是Windows

显示的时间 - 并且存在不兼容性。


这是一个错误吗?

I tried this on Windows only:

In Python 2.4 os.path.getmtime returned the local time,
in Python 2.5 it seems to return GMT:

import os, time
print ctime.time(os.path.getmtime(foo))

differs on Python 2.4 and Python 2.5 by the timezone.

Now, the implementation of the two stat calls differs on Windows
between the two versions.

I actually like the new behaviour better, because I believe the
reported time of a file should not depend on the timezone or other
local settings, however the old behaviour is the time also Windows
shows - and there is an incompatibility.

Is this a bug?

为什么你没看过之前发布的回复? John Machin

回复(< 11 ********************** @ l77g2000hsb.googlegroups .com>)

你错了:Py2.5和Py2.4之间的结果

of os.path.getmtime没有区别。它总是返回

UTC,并且永远都会。


问候,

Why don''t you read the responses posted earlier? John Machin
replied (in <11**********************@l77g2000hsb.googlegroups .com>)
that you are mistaken: There is NO difference between the outcome
of os.path.getmtime between Py2.5 and Py2.4. It always did return
UTC, and always will.

This is python 2.4.4 and Python 2.5.1 on windows XP.
The reported time clearly differs.

我认为你的意思是time.ctime :-)

您没有提供任何证据。您是否阅读了我之前的
