   The following example shows a DAG scheduled in a timezone different from the macros (which use UTC), causing a **date mismatch**. 
   
   ```
   ENV TZ=Europe/Amsterdam
   ENV AIRFLOW__CORE__DEFAULT_TIMEZONE=Europe/Amsterdam
   ```
   
   ```python
   from airflow import models
   from airflow.operators.bash_operator import BashOperator
   
   default_args = {
       'owner': 'airflow',
       'depends_on_past': False,
       'start_date': datetime(2020, 1, 1),
       'catchup': False,
       'retries': 0,
   }
   
   with models.DAG(
       'example_timezone',
       schedule_interval='0 0 * * *', # Schedules DAG at 0:0 in Europe/Amsterdam timezone (e.g. 29.9.2020 00:00)
       doc_md=__doc__,
       default_args=default_args,
       catchup=False,
   ) as dag:
   
       print_date = BashOperator(
           task_id='print_date',
           bash_command='date', # Prints date with timezone Europe/Amsterdam (e.g. 29.9.2020 00:00)
       )
       execution_date_tz = BashOperator(
           task_id='execution_date_tz',
           bash_command="echo {{ execution_date.in_timezone('Europe/Amsterdam') }}", # Prints date with timezone Europe/Amsterdam (e.g. 29.9.2020 00:00)
       )
       execution_date = BashOperator(
           task_id='execution_date',
           bash_command='echo {{ execution_date }}', # Prints date with timezone UTC (e.g. 28.9.2020 22:00)
       )
       ds = BashOperator(
           task_id='execution_date_tz',
           bash_command="echo {{ ds }}", # Prints date with timezone UTC (e.g. 28.9.2020)
       )
       print_date >> execution_date >> execution_date_tz >> ds
   
   ```
   
   
   > Note: as reference, the Azure devops scheduler is always in UTC. But we are a single timezone company and it would be comfortable to have everything in one zone.
