Django在Celery中的定期任务

Question

i"m having this issue with periodic tasks not running. I"m using redis as a backend and can run the tasks manually, this is the celery debug log

[ModelEntry: myproject.myapp.tasks.MyPeriodicTask myproject.myapp.tasks.MyPeriodicTask(*[], **{}) { freq: 10.00 seconds }]
    [2012-08-01 13:45:53,764: DEBUG/MainProcess] Consumer: Ready to accept tasks!
    [2012-08-01 13:45:53,801: DEBUG/Beat] Celerybeat: Ticking with max interval->5.00 seconds
    [2012-08-01 13:45:53,808: DEBUG/Beat] Celerybeat: Waking up in 5.00 seconds.
    [2012-08-01 13:45:58,814: DEBUG/Beat] Celerybeat: Waking up in 5.00 seconds.
    [2012-08-01 13:46:03,828: DEBUG/Beat] Celerybeat: Waking up in 5.00 seconds.

When i run the task manually, everything works. Timezone is the same in django and celery

As reported in Celery issue #4184 , you can solve this problem by changing CELERY_TIMEZONE to UTC. I experienced a similar problem, but with the database scheduler, and this resolved it for me.
