   I think I found what might be problem.
   In scheduler_job.py around line number 1210 "#Check state of finished tasks" it queries task_instances table but with wrong filter parameter. Time is one hour behind. In task_instances table I see the dag run with success state and execution date e.g. 14 o'clock and filter in scheduler_job.py is filtering for 13 o'clock. and 14 o'clock is the correct time, so time that is written in task_instances table is correct. The filter time is wrong.
   But I didn't yet figure out where that date is setup. Maybe some of you will know that by heart? :)
   
   In airflow.cfg default_timezone = Europe/Zagreb and that's consistent with the task_instances execution_date time.
   
   Even though, AFAIK Airflow should store everything in utc internally which means that the time saved in database is not correct, right?
