This comes down to the intended behaviour of [moment-timezone](https://github.com/moment/moment-timezone), the JS package used for handling timezones in the UI. Here's the part of the source which populates that field: https://github.com/apache/airflow/blob/dd386c81f50fe2a93cf0bff0c3da2c66f2dc6e6a/airflow/www/static/js/datetime_utils.js#L23-L33 You can replicate this behaviour by running the relevant line of code in the javascript console of the Airflow webserver: ```javascript > moment().tz("America/Vancouver").format('z (Z)') "PDT (-07:00)" > moment().tz("Chile/Continental").format('z (Z)') "-04 (-04:00)" ``` Looking into the discussion in [this issue](https://github.com/moment/moment-timezone/issues/841) on moment-timezone, I believe that this is intended behaviour for some timezones due to this [ICANN change from 2017](https://mm.icann.org/pipermail/tz-announce/2017-February/000045.html) in which it was decided to use numeric abbreviations for many South American time zones: -- This is an automated message from the Apache Git Service.
