1. 1. 1. Summary

The `backup_plan` module is not idempotent on botocore >= 1.31.36. This is because timezone customization support was added for rules (https://github.com/boto/boto3/blob/86426e872033d2d03e083fa53848e53d099ebcde/CHANGELOG.rst#L1112). The `ScheduleExpressionTimezone` field is always returned when describing a backup plan and defaults to `Etc/UTC`.
