How to Keep Utc Time in Logging While Changing the Time_Zone Settings?

Django uses Python's logging facilities, so there shouldn't be anything Django-specific here.

According to the logging documentation, setting logging.Formatter.converter = time.gmtime should make all logs output in UTC.

Alternatively, you can make your own Formatter class to use UTC:

class UtcFormatter(logging.Formatter): 
    converter = time.gmtime

And then configure it using the () key (documented here) in the dictconfig:

LOGGING = {
    'formatters': {
        'utc': { 
            '()': 'my.package.UtcFormatter',
            'format': '...',
            'datefmt': '...',
        }
    }
}
