title: Apache Airflow dag schedules in midnight UTC
body: <p>I created Apache Airflow DAG with following default args. I want this DAG to run every day at 10PM UTC but it's always running at 12AM UTC and ignoring the date time I had set in start_date. Is this not the right way? Thanks.</p>
  
  <pre><code>default_args = {
      'owner': config.OWNER,
      'depends_on_past': False,
      'start_date': datetime(2018, 10, 14, 22, 0, 0),
      'email': [config.ALERT_EMAIL],
      'email_on_failure': True,
      'email_on_retry': False,
      'retry_delay': timedelta(minutes=1),
      'retries': 2,
  }
  
  # DAG
  dag = DAG('Test',
            default_args=default_args,
            description='Initial setup',
            schedule_interval='@daily')
  </code></pre>
