xmduhan opened a new issue #20315:
URL: https://github.com/apache/airflow/issues/20315
### Apache Airflow version
2.2.2 (latest released)
### What happened
* (1). When I set airflow.cfg with:
default_ui_timezone = Asia/Shanghai
default_timezone = Asia/Shanghai
* (2). start weserver and scheduler
* (3). trigger "example_bash_operator" task manually
* (4). in upper right corner select ui display timezone with "CST +(08:00)"
* (5). I find task log time in web page is wrong, it faster 8 hours than
it real is.
### What you expected to happen
* In web page it shdould display the correct log time.
### How to reproduce
* As described In "What happened".
* I think this is cause by the logger use localtime but not UTC. Why should
we save all time with UTC in database but localtime in log?
### Operating System
Ubuntu 20
### Versions of Apache Airflow Providers
apache-airflow-providers-ftp==2.0.1
apache-airflow-providers-http==2.0.1

apache-airflow-providers-sqlite==2.0.1
### Deployment
Other
### Deployment details
pip freeze | grep apache-airflow-providers
### Anything else
I think it's can be fixed by add a UTCFromatter for logger.
edit file "airflow/airflow/config_templates/airflow_local_settings.py"
``` python
+import logging
+import time
+
+class UTCFormatter(logging.Formatter):
+ converter = time.gmtime
+
DEFAULT_LOGGING_CONFIG: Dict[str, Any] = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
- 'airflow': {'format': LOG_FORMAT},
+ 'airflow': {'()': UTCFormatter, 'format': LOG_FORMAT},
```
