Siddharth Anand commented on AIRFLOW-43:
----------------------------------------

Yes, it is currently a requirement until someone takes on the work to make it work in any timezone (and possibly across timezones). 
Refer to https://cwiki.apache.org/confluence/display/AIRFLOW/Common+Pitfalls

>                 Key: AIRFLOW-43
>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-43
>             Project: Apache Airflow
>          Issue Type: Bug
>    Affects Versions: Airflow 1.7.0
>         Environment: OSX, Python 2.7.5
>            Reporter: Chris Johnson
>            Assignee: Siddharth Anand
>            Priority: Critical
>
> I have a DAG which should only be run as needed (no schedule interval):
> dag = DAG(
>     dag_id='major_integ_cycle',
>     default_args=args,
>     schedule_interval=None,
> )
> I attempted to start this using `airflow trigger_dag NAME` but the tasks never run.  The scheduler has noted the fact that itthe DAG was triggered: INFO - Created <DagRun major_integ_cycle @ 2016-05-03 08:36:16.032474: manual__2016-05-03T08:36:16.032474, externally triggered: True>
> The tasks are currently very vanilla test cases, all look like this:
> task_mdc = op.BashOperator(
>     task_id='master_data_cycle',
>     bash_command='sleep 1',
>     dag=dag,
> )
> Have I misunderstood?  Or is not running a bug in this case?
