Context (please complete the following information):

• OS: any
• Browser NA
• Browser Version NA
• Python Version 3.12
• GeoHealthCheck Version master on June 26, 2026

If running with Docker:

• Docker installed version
• GeoHealthCheck Docker Image version : latest

**Analysis
I suspect this happens since tzlocal upgrade to latest version related to APScheduler. The previous was tzlocal<3.0
Now:

 tzdata                         2025c        hc9c84f9_1          conda-forge
  tzlocal                        5.4.3        pypi_0              pypi 

See YelpArchive/elastalert#2968

Plus seems to happen only on existing databases, i.e. jobs stored.
Suspect difference/mismatch between: "Offset-naive and Offset-aware datetimes".
Newly added jobs work ok, like this local instance:

In the end the fix was simple, always set a timezone for the DB attribute (which is UTC anyway, but without TZ info as set by SQLAlchemy):

end_time = self.end_time.replace(tzinfo=timezone.utc)
        return now > end_time

Now APScheduler works again agains existing data! Has to do with ResourceLock which is not always needed. For example:
