call-date-fromtimestamp (DTZ012)
Derived from the flake8-datetimez linter.
What it does
Checks for usage of datetime.date.fromtimestamp()
.
Why is this bad?
Python date objects are naive, that is, not 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.date.fromtimestamp(ts)
returns a naive date object.
Instead, use datetime.datetime.fromtimestamp(ts, tz=...).date()
to
create a timezone-aware datetime object and retrieve its date component.
Example
Use instead:
Or, for Python 3.11 and later:
