How to generate aware time object in Faker?

Question

I have the following (simplified) model and factory:

models.py

class Event():
    duration = FloatField()
    start_time = TimeField()
    finish_time = DateTimeField()

    def save(self, *args, **kwargs):
        self.finish_time = self.start_time + timedelta(hours=self.duration)

event_factory.py

from factory import Faker

class EventFactory:
    date = Faker(
        "date_time_this_month",
        before_now=False,
        after_now=True,
        tzinfo=timezone.get_current_timezone(),
        )
    start_time = Faker("time_object")
    duration = Faker("random_int")

However, my save method raises Warning: DateTimeField Event.finish_time received a naive datetime (2022-03-28 12:43:38) while time zone support is active.

date is aware due to tzinfo argument, but start_time is naive (I checked with django's timezone.is_aware()), because time providers in Faker do not seem to allow any timezone parameters.

Any suggestion in getting a fake aware time object in factory-boy/Faker?

Try to use FuzzyDateTime objects, they return a timezone aware object: https://factoryboy.readthedocs.io/en/stable/fuzzy.html?highlight=timezone
