Jakub Powierza commented on AIRFLOW-3354:
-----------------------------------------
You're right - I'll double check why we do so. I found it while upgrading
Airflow to the newest version and thought it may be useful for you.
Feel free to close this issue if you think that it is not a bug on your side!
Thanks for your time and sorry for false alarm!

> Key: AIRFLOW-3354
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3354
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: 1.10.1
> Reporter: Jakub Powierza
> Priority: Major
>
> New version of Airflow (1.10.1rc1 and 1.10.1rc2) tries to compare
> offset-naive and offset-aware dates in Scheduler. I've tested a simple case
> with schedule set to "*/10 * * * *". I've tried to clean my developer
> instance with `airflow resetdb` and start from scratch but it does not help
> at all. This issue does not occur on stable version 1.10.0.
> My setup: Python 3.6 on Ubuntu 14.04 with Airflow Scheduler based on Celery
> with RabbitMQ backend.
> Exception found in Scheduler logs:
> {code:java}
> 2018-11-15 14:41:23,194:ERROR:airflow.processor:[CT=None] Got an exception!
