This rule raises an issue when trying to perform comparison or arithmetic operations between `offset-naive` and `offset-aware` Datetimes.

== Why is this an issue?

`datetime.datetime` and `datetime.time` objects may be categorized as "aware" or "naive" depending on whether or not they include timezone information.

Comparison or arithmetic operations between `offset-naive` and `offset-aware` datetimes raise a `TypeError`.

== How to fix it
Perform comparison or arithmetic operations only between offset-naive or only between offset-aware Datetimes.

=== Code examples

==== Noncompliant code example

[source,python,diff-id=1,diff-type=noncompliant]
----
import datetime
from pytz import timezone

tz = timezone('America/New_York')
dt1 = datetime.datetime(2023, 5, 23, tzinfo=tz)
dt2 = datetime.datetime(2023, 5, 24)

if dt1 < dt2: # Noncompliant: TypeError: can't compare offset-naive and offset-aware datetimes
    ...
----

==== Compliant solution

[source,python,diff-id=1,diff-type=compliant]
----
import datetime
from pytz import timezone

tz = timezone('America/New_York')
dt1 = datetime.datetime(2023, 5, 23, tzinfo=tz)
dt2 = datetime.datetime(2023, 5, 24, timezone.utc)

if dt1 < dt2: # OK
    ...
