if task.timeout > timedelta(hours=48):
task.timeout = timedelta(hours=48)

To define policy, add a ``airflow_local_settings`` module to your PYTHONPATH
or to AIRFLOW_HOME/config folder that defines this ``policy`` function. It receives a ``TaskInstance``
object and can alter it where needed.

Please note, cluster policy currently applies to task only though you can access DAG via ``task.dag`` property.
Also, cluster policy will have precedence over task attributes defined in DAG
meaning if ``task.sla`` is defined in dag and also mutated via cluster policy then later will have precedence.
