我不断收到此错误：
时区"东部标准时间"无法识别
这是代码：
def get_context_data(self, **kwargs):
# Call the base implementation first to get a context
context = super(IndexView, self).get_context_data(**kwargs)
"""Return the last five published posts."""
context['latest_post_list'] = Post.objects.order_by('-pub_date')[:5]
context['archives'] = Post.objects.datetimes('pub_date', 'month', order='DESC')
return context;
在我的模板中：
{% for archive in archives %}
<li><a href="#">{{ archive.month }} {{ archive.year }}</a></li>
{% endfor %}
在我的设置中：
TIME_ZONE = 'America/Montreal'
我想做的是建立某种存档系统。在可以获得不同月份和年份的地方，有任何帖子。

安装pytz，错误消失：
pip install pytz
这可能是仅限 Windows 的问题，请参阅注释 https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-TIME_ZONE。
这
真的很难说，因为我看不到您的数据，但看起来您在时区的数据字段/列中有"东部标准时间"。
Python 通过 pytz 包使用 IANA/Olson 时区。 因此，您的数据应具有美国东部时间的"美国/New_York"。
