Comment 2 for bug 1469563

https://review.openstack.org/#/c/192739/ includes a new test called test_rescoping_token() which should be triggering this behavior, but it's running into bug 1459790 instead of the issue described here, even when I add a time.sleep() to the parent class' test. The microseconds simply differ between a zero and non-zero value, because Fernet cannot persist microseconds.

If this issue is truly distinct from bug 1459790, how do we reproduce it that differs from test_rescoping_token()?
