Hi must include the following information when creating a new timezone connection in Airflow: Here are some documentation that might help you. You can try running your DAG once more after adding this configuration to see if the logs reflect the proper timezone. The 'timezone' connection and 'AIRFLOW_CORE_TIMEZONE' variable are set to 'Europe/Lisbon' in this arrangement, which the Airflow scheduler and employees should recognize. Enter 'AIRFLOW_CORE_TIMEZONE' as the key and 'Europe/Lisbon' as the value.Go to the 'Variables' tab and click on 'Create'.Enter 'timezone' as the connection ID and 'Europe/Lisbon' as the value for the 'Extra' field.Click on 'Connections' and then click on 'Create'.Go to the Airflow UI and click on the 'Admin' tab.This can be done by including the subsequent configuration in the Airflow UI: You may also try adjusting the Airflow scheduler and workers' timezone environment variable to 'Europe/Lisbon' to address this problem. To change the timezone for certain components, altering the Composer settings might not be sufficient. The Airflow scheduler and workers, independent processes running on different computers than the Composer environment, produce the Airflow logs may be one factor contributing to this problem. It appears that even after changing the timezone in the Composer properties and making your DAG timezone aware, your Airflow logs are still displaying UTC time. INFO - 1 downstream tasks scheduled from follow-on schedule check As example, looking for Task Log, the AIRFLOW_CTX_EXECUTION_DATE is still in UTC: (.)ĪIRFLOW_CTX_EXECUTION_DATE=T11:58:00+00:00 It seams that internally Composer is not using my timezone as Default. The DAG being executed accordly with the cron on my timezone - Scheduling: OK The Webserver UI is presented in my timezone - WebUI: OK The scheduled is working accordley with my timezone. I am using pendulum library, and specifying timezone. Webserver - default_ui_timezone: 'Europe/Lisbon' I know that, by default, Composer uses timedates in UTC timezone, so I alredy proceed on some steps to change that, but, without being able to change in all components.ġ Change Composer properties - Airflow Configuration Overwrites - with values: What I want to do is to change Airflow, in all its components, to reflect my Time Zone: 'Europe/Lisbon'.
