If you plan to construct a bunch of datetimes and query their time zone information relatively infrequently (an average of 2-3 times per datetime), it seems that dateutil beats pytz in "total time to first utcoffset call": The story is similar for converting from one time zone to another (though pytz does better than I would expect): dateutil is slower in this operation because it needs to calculate the UTC offset for both New York and Los Angeles, and pytz evidently is faster at creating localized datetimes from UTC than from naive datetimes (otherwise I would expect to pay at least the cost of another localize). Drop-in replacement for native datetime objects. More information can be found on our Code of Conduct page.
