call-datetime-utcnow (DTZ003)#

Derived from the flake8-datetimez linter.

What it does#

Checks for usage of datetime.datetime.utcnow().

Why is this bad?#

Python datetime objects can be naive or timezone-aware. While an aware object represents a specific moment in time, a naive object does not contain enough information to unambiguously locate itself relative to other datetime objects. Since this can lead to errors, it is recommended to always use timezone-aware objects.

datetime.datetime.utcnow() returns a naive datetime object; instead, use to create a timezone-aware object.


import datetime


Use instead:

import datetime

Or, for Python 3.11 and later:

import datetime
