So it seems that we create a string like "Sat Mar 10 09:00:00 2018", but the python version we compare with gives "03/10/18 09:00:00". According to docs for %c, the former (our result) is actually correct.
But since we are checking matching results in Python in this test, just skipping the ones where those don't match.

So it seems that we create a string like "Sat Mar 10 09:00:00 2018", but the python version we compare with gives "03/10/18 09:00:00". According to docs for %c, the former (our result) is actually correct.

But since we are checking matching results in Python in this test, just skipping the ones where those don't match.

So it seems that we create a string like "Sat Mar 10 09:00:00 2018", but the python version we compare with gives "03/10/18 09:00:00". According to docs for %c, the former (our result) is actually correct.

But since we are checking matching results in Python in this test, just skipping the ones where those don't match.

So it seems that we create a string like "Sat Mar 10 09:00:00 2018", but the python version we compare with gives "03/10/18 09:00:00". According to docs for %c, the former (our result) is actually correct.

But since we are checking matching results in Python in this test, just skipping the ones where those don't match.
