Failing tests due to timing

[wkoot]

Describe the bug Various tests failing due to timing inconsistency/bug (on Windows):

• collector_utilities.test_date_time.DaysToGoTest
  • test_next_week: 8 != 7
  • test_now: 1 != 0

However, at 14:45 15-12-2023:

• collector_utilities.test_date_time.DaysToGoTest
  • test_next_week: 8 != 7
  • test_tomorrow: 2 != 1

======= Previously also failing tests, fixed by #7680:

• source_collectors.trello.test_issues.TrelloIssuesTest
  • test_issues and test_overdue_issues fail due to Exception
  • issues.py, line 34, in card_is_overdue return due_date < now()
  • tz.py, line 222, in utcoffset if self._isdst(dt):
  • tz.py, line 291, in _isdst dstval = self._naive_is_dst(dt)
  • tz.py, line 260, in _naive_is_dst return time.localtime(timestamp + time.timezone).tm_isdst
  • OSError: [Errno 22] Invalid argument
• source_collectors.azure_devops.test_source_up_to_dateness.AzureDevopsSourceUpToDatenessTest
  • test_age_of_pipeline and test_no_file_path_and_no_pipelines_specified
  • One day offset just after midnight: '1491' != '1490'
