### Under which category would you file this issue? Providers ### Apache Airflow version 3.1.8 ### What happened and how to reproduce it? ### Summary Importing `SFTPSensor` (from `apache-airflow-providers-sftp`) on Airflow 3.1.8 with Python 3.11 causes `DeprecatedImportWarning` due to usage of `airflow.utils.timezone` in SFTP provider code. <img width="1139" height="225" alt="Image" src="https://github.com/user-attachments/assets/c8fd0010-e261-4376-a4e6-2b0d20d920d1"; /> ### Current Behavior On importing or using SFTPSensor, log shows: [2026-04-17 18:35:28] INFO - Filling up the DagBag from /mnt/local/airflow/dagcodes/dags/utility/test.py [2026-04-17 18:35:28] WARNING - The `airflow.utils.timezone.convert_to_utc` attribute is deprecated. Please use `'airflow.sdk.timezone.convert_to_utc'`. category=DeprecatedImportWarning [2026-04-17 18:35:28] WARNING - The `airflow.utils.timezone.convert_to_utc` attribute is deprecated. Please use `'airflow.sdk.timezone.convert_to_utc'`. category=DeprecatedImportWarning [2026-04-17 18:35:28] WARNING - The `airflow.utils.timezone.parse` attribute is deprecated. Please use `'airflow.sdk.timezone.parse'`. category=DeprecatedImportWarning ### Reproduction Steps 1. Airflow version: `3.1.8` 2. Python version: `3.11` 3. Executor/environment: `Celery` 4. Minimal DAG: ```python from datetime import datetime from airflow.sdk import DAG from airflow.providers.sftp.sensors.sftp import SFTPSensor with DAG( dag_id="repro_sftp_timezone_warning", start_date=datetime(2024, 1, 1), schedule=None, catchup=False, ): SFTPSensor( task_id="wait_for_file", path="/tmp/somefile.txt", sftp_conn_id="sftp_default", ) ``` ### Analysis providers/sftp/src/airflow/providers/sftp/sensors/sftp.py imports deprecated timezone path. Link: [sftp.py](https://github.com/apache/airflow/blob/main/providers/sftp/src/airflow/providers/sftp/sensors/sftp.py#L32) Same behavior observed in provider releases including apache-airflow-providers-sftp==5.7.0 and 5.7.3. Link: [sftp_5.7.3.py](https://airflow.apache.org/docs/apache-airflow-providers-sftp/stable/_modules/airflow/providers/sftp/sensors/sftp.html) ### What you think should happen instead? No DeprecatedImportWarning should be emitted from provider internals on Airflow 3.x. Replace deprecated airflow.utils.timezone imports/usages with airflow.sdk.timezone in SFTP provider sensor(s). ### Operating System _No response_ ### Deployment Docker-Compose ### Apache Airflow Provider(s) sftp ### Versions of Apache Airflow Providers `apache-airflow-providers-sftp 5.7.0 ` ### Official Helm Chart version Not Applicable ### Kubernetes Version _No response_ ### Helm Chart configuration _No response_ ### Docker Image customizations _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
