I'm trying to implement timezone awareness in my Python application, and I have come across two different Python modules that implement this feature: pytz and python-dateutil. What is the difference between these two modules?
(pytz) http://pytz.sourceforge.net/
(dateutil) https://dateutil.readthedocs.io/en/stable/
They both provide useful support for dealing with timezones. I've personally used pytz in my django applications and found it useful and easy to work with. Hope my two cents helps.
