我已经用PostgreSQL安装了3台服务器，到目前为止还没有看到这个问题.我现在正在设置第一台不在丹麦服务器上运行的服务器，从web访问数据库时，我开始出错.
我可以使用createsuperuser而没有问题，它创建了我的超级用户.但当我试图使用它登录我的网站时，我得到了错误.

AssertionError: database connection isn't set to UTC
我一直在看代码，错误来自这个代码.
from django.utils.timezone import utc
def utc_tzinfo_factory(offset):
if offset != 0:
raise AssertionError("database connection isn't set to UTC")
return utc
虽然我找不到偏移是从哪里开始的，所以我不知道Django是如何决定我的偏移是关闭的.
我的postgresql数据库将时区设置为UTC，并验证了django文档中编写的所有postgresql参数，我现在不知道为什么会发生这种情况.
我希望这里有人能帮忙？

django管理--版本:1.9.2
UPDATED 11/8-2016 - Full Stack from DEBUG view
我在utc_tzinfo_工厂中找到了偏移量的值，它的值为120.尽管我无法解释它是如何或为什么得到这个值的.
下面是Django调试页面的副本，用于完整堆栈和变量的错误.
