27687	Dateformat issue using django basic logging formatter	Ahn ByungHyun	nobody	"I'm using django v1.10.4 with python 3.5.2 and write Logging setting in setting.py.

I faced some problem using log formatter.

I want to present date format of log like `'%Y-%m-%d %H:%M:%S.%f%z'` but `%f` doesn't work.

My formatters setting is like this. 
{{{
'formatters': {
        'verbose': {
            'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s',
            'datefmt':'%Y-%m-%d %H:%M:%S.%f%z',
        },
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
    },
}}}
The log `%(asctime)s` is printed ""2017-01-05 13:54:24.f+0900""

Is this bug? or intended behavior?"	Uncategorized	closed	Utilities	1.10	Normal	invalid	logging formatter datefmt		Unreviewed	0	0	0	0	0	0
