Timezone-aware schedule with @asset decorator

[aglebov]

I'm trying to use this example from https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/assets.html#dependency-between-asset-task-and-classic-operators to define an asset together with a BashOperator that creates it:

@asset(schedule=None)
@task.bash(retries=3)
def example_asset():
    """Write to example_asset, from a Bash task with 3 retries..."""
    return "echo 'run'"

I'd like to specify a schedule, e.g. 0 9 * * *, with a timezone. In an explicit DAG definition, this could be achieved with

DAG(
    dag_id='my_dag',
    start_date=pendulum.datetime(2026, 2, 15, tzinfo=pendulum.timezone('Europe/London')),
    schedule='0 9 * * *',
)

however @asset does not seem to accept start_date as an argument. Is there another way to achieve this with @asset?
