在python和时区问题中启动python [英] Launching python within python and timezone issue

问题描述

我必须为我的django应用制作启动程序脚本，而且似乎以某种方式将时区切换为GMT(默认值为+2)，并且使用该脚本时每个日期时间都晚了两个小时.可能是什么原因造成的?

I had to make a launcher script for my django app, and it seems it somehow switches the timezone to GMT (default being +2), and every datetime is two hours behind when using the script. What could be causing that?

这是我使用的启动脚本:

Here is the launcher script that I use:

#!/usr/bin/env python

import os
import subprocess
import shlex
import time

cwd = os.getcwd()

p1 = subprocess.Popen(shlex.split("python manage.py runserver"),
        cwd=os.path.join(cwd, "drugsworld"))
p2 = subprocess.Popen(shlex.split("python coffee_auto_compiler.py"),
        cwd=os.path.join(cwd))

try:
    while True:
        time.sleep(2)
except KeyboardInterrupt:
    p1.terminate()
    p2.terminate()

如果我手动运行 python manage.py runserver ，则时区为+2.但是，如果我使用此脚本，则时区设置为GMT.

If I manually run python manage.py runserver, the timezone is +2. If, however, I use this script, the timezone is set to GMT.

推荐答案

嗯.Python尊重TZ环境变量...您并未在脚本中对其进行更改，因此它应等同于在shell上运行它.

Hmm. Python respects the TZ environment variable... you're not changing it in your script, so it should be equivalent to running it at the shell.

我经常明确设置时区.特别是在Django中，您可以在settings.py文件(TIME_ZONE)中进行设置.更通用的python是:

I often set the time zone explicitly. In Django specifically, you can set this in the settings.py file (TIME_ZONE). More general python is:

os.environ['TZ']="America/New_York"
time.tzset()

我想如果您在设置文件中设置时区，问题将会消失.

I imagine if you set the timezone in your settings file, the problem will go away.
