我使用 Django 1.6 和 Celery 3.1.11 运行在线游戏。Kombu 是 3.0.15。

最近我遇到了 Celery 和 DST 的问题，所以我决定在 UTC 上运行整个站点，这样我就不用担心时区了。

我的settings.py的相关部分：

TIME_ZONE = 'UTC'
USE_TZ = True
....
CELERY_ENABLE_UTC = True
CELERY_TIMEZONE = 'UTC'

现在，每当我发送任何延迟的任务时，我都会看到一堆 RuntimeWarnings 抱怨天真的日期时间。我进入了我的 settings.py 并将其变成了一个异常，这是导致的回溯：

[2014-04-18 15:03:49,748: INFO/MainProcess] Received task: sometask[sometaskid] eta:[2014-04-19 00:33:32.410032+00:00]

如您所见，没有任何回溯是由于我的代码，所以我不知道如何继续。我只能留下警告（如果我没记错的话，Celery 将时间偏移默认设置为CELERY_TIMEZONEsettings.py 中的内容，无论如何这就是我想要的），但我的强迫症正向我尖叫着要解决这个问题。另外，我无法通过 ctrl-F 找到任何由于我的代码引起的警告。

有什么建议吗？
