我一直收到这个错误：
时区“东部标准时间”未被识别
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'
我想做的是获得某种存档系统。如果有可能获得不同的月份和年份，那么就有任何帖子。

已安装pytz，错误消失了：
pip install pytz
这可能是仅限Windows的问题，请参阅说明https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-TIME_ZONE。

由于我无法看到您的数据，因此很难分辨，但看起来您在某个时区的数据字段/列中有“东部标准时间”。
Python通过IANA/Olson time zones使用the pytz package。所以你的数据在美国东部时间应该有“America / New_York”。
