   This is likely not an issue with timetable logic in Airflow but logic error in user code, so I’m converting this to a discussion. The timezone change is entirely in the wrong place; all Airflow datetimes are UTC internally, so doing `replace(tzinfo=CST)` is totally not the right thing to do and will give you nonsensical results. Instead, you should convert the datetimes _passed into timetable functions_ to your target timezone instead, before you perform any logic.
