call-datetime-without-tzinfo (DTZ001)#
Derived from the flake8-datetimez linter.
What it does#
Checks for datetime
instantiations that lack a tzinfo
argument.
Why is this bad?#
datetime
objects are "naive" by default, in that they do not include
timezone information. "Naive" objects are easy to understand, but ignore
some aspects of reality, which can lead to subtle bugs. Timezone-aware
datetime
objects are preferred, as they represent a specific moment in
time, unlike "naive" objects.
By providing a tzinfo
value, a datetime
can be made timezone-aware.
Example#

Or, for Python 3.11 and later:
