To be clear, when I wrote this article, I had not yet created the `zoneinfo` module in the standard library. All the recommendations for `dateutil.tz` apply to `zoneinfo` as well, except that `zoneinfo` is also faster than `pytz`.
Thank you so much for your work on zoneinfo. I spend my days working on a legacy Django app and can't wait to switch from pytz to zoneinfo. In my experience, timezones are always a struggle so your efforts to make them easier to deal with is hugely appreciated.
