title: celerybeat uses UTC even with timezone settings
body: <p>I'm finding that celerybeat is using UTC time in its scheduling (and outputting logs in UK time?!) even though I believe I have the required settings in my django settings.py:</p>
  
  <pre><code>TIME_ZONE = 'UTC'
  USE_TZ = True
  CELERY_ENABLE_UTC = True
  CELERY_TIMEZONE = 'Australia/Sydney'
  CELERYBEAT_SCHEDULE = 
      "testRunBeat" : {
          "task" : "experiments.tasks.testHeartBeat",
          "schedule" : crontab(minute = "*/1", hour="13-14"),    
  }
  </code></pre>
  
  <p>I have tried switching the TIME_ZONE variable with no luck</p>
  
  <p>I am using:</p>
  
  <pre><code>django==1.4
  celery==2.5.5
  django-celery==2.5.5
  </code></pre>
  
  <p>Thanks</p>
