[Bug 1891517] [NEW] neutron.tests.unit.common.test_utils.TimerTestCase.test__enter_with_timeout fails once in a while

 

Public bug reported:

While running job openstack-tox-lower-constraints

https://zuul.opendev.org/t/openstack/job/openstack-tox-lower-constraints

I see intermittent failures that look lie this:

neutron.tests.unit.common.test_utils.TimerTestCase.test__enter_with_timeout
---------------------------------------------------------------------------

Captured traceback:

~~~~~~~~~~~~~~~~~~~

The code needs to do better in the rounding of the second. ;)
