Too Fast! Python's so fast that my test_course_creation test keeps failing...

In testing the Course model using the code in the video, I get an error message like the one below. I guess, while all of the 5 tests take a total of 31 milliseconds to complete, the speed with which Python goes from creating a Course instance to the "now" variable is less than a millisecond... so that the "self.assertLess(course.created_at, now)" produces the following error:

AssertionError: datetime.datetime(2017, 8, 19, 4, 36, 15, 156198, tzinfo=<UTC>) not less than datetime.datetime(2017, 8, 19, 4, 36, 15, 156198, tzinfo=<UTC>)

----------------------------------------------------------------------
Ran 5 tests in 0.031s

Both datetime objects have the same time... even to the millisecond.

I changed the "assertLess" to "assertLessEqual" and the test passed.
Just fyi in case others have this same issue. Thanks! D.
