Django基于Pycharm开发之三[LANGUAGE_CODE与TIME

在django/conf/global_settings.py 中，我们可以找到关于language和timezone的通用配置信息，源码如下：

# Local time zone for this installation. All choices can be found here:


	# https://en.wikipedia.org/wiki/List_of_tz_zones_by_name (although not all
	# systems may support all possibilities). When USE_TZ is True, this is
	# interpreted as the default user time zone.
	TIME_ZONE = 'America/Chicago'

	# If you set this to True, Django will use timezone-aware datetimes.
	USE_TZ = False

	# Language code for this installation. All choices can be found here:
	# http://www.i18nguy.com/unicode/language-identifiers.html
	LANGUAGE_CODE = 'en-us'

	# Languages we provide translations for, out of the box.

在这里，我们可以找到关于language_code的缩写，对应的关于time_zone,我们可以在这里找到相关信息

#something you want can find by https://github.com/django/django/blob/master/django/conf/global_settings.py
# Local time zone for this installation. All choices can be found here:
# https://en.wikipedia.org/wiki/List_of_tz_zones_by_name (although not all
# systems may support all possibilities). When USE_TZ is True, this is
# interpreted as the default user time zone.

`TIME_ZONE`

Default: 'America/Chicago'

A string representing the time zone for this installation. See the list of time zones.

Note

Since Django was first released with the TIME_ZONE set to 'America/Chicago', the global setting (used if nothing is defined in your project’s settings.py) remains 'America/Chicago' for backwards compatibility. New project templates default to 'UTC'.

Note that this isn’t necessarily the time zone of the server. For example, one server may serve multiple Django-powered sites, each with a separate time zone setting.

When USE_TZ is False, this is the time zone in which Django will store all datetimes. When USE_TZ is True, this is the default time zone that Django will use to display datetimes in templates and to interpret datetimes entered in forms.

On Unix environments (where time.tzset() is implemented), Django sets the os.environ['TZ'] variable to the time zone you specify in the TIME_ZONE setting. Thus, all your views and models will automatically operate in this time zone. However, Django won’t set the TZ environment variable if you’re using the manual configuration option as described in manually configuring settings. If Django doesn’t set the TZ environment variable, it’s up to you to ensure your processes are running in the correct environment.

Note

Django cannot reliably use alternate time zones in a Windows environment. If you’re running Django on Windows, TIME_ZONE must be set to match the system time zone.

看看官方这段的描述，所以当我们使用windows开发的时候，还是要注意以上的一些问题的。
