[BUG] Timezone shenanigans with Django

[rijenkii]

Describe the bug When trying to run prospector on a Django project, "Finished" time seems to be taken from another time zone.

To Reproduce

$ django-admin startproject prospector_test
$ cd prospector_test
$ DJANGO_SETTINGS_MODULE=prospector_test.settings prospector
...

         Started: 2022-04-01 20:24:26.097744
        Finished: 2022-04-01 13:24:27.867276
      Time Taken: -25198.23 seconds

Expected behavior Following is taken from prospector output when ran without DJANGO_SETTINGS_MODULE:

=================
         Started: 2022-04-01 20:21:34.312963
        Finished: 2022-04-01 20:21:36.034789
      Time Taken: 1.72 seconds

Environment (please complete the following information):

• OS: Linux
• Tool: probably pylint, as when I do not specify DJANGO_SETTINGS_MODULE time is calculated as expected
• Prospector version: 1.1.7
• Python version: 3.10.2

Additional information

I am in a UTC+7 time zone, so it seems that "Finished" time is from UTC+0.
