tests.common.test_format_utils.TestFormatTimestamp fails on Ubuntu Trusty #52

Closed mjeanson closed 8 years ago

mjeanson commented 8 years ago

On an Ubuntu Trusty 14.04, the tests.common.test_format_utils.TestFormatTimestamp fails with a delta of one second. The tzdata version on this system is 2016d-0ubuntu0.14.04 while it works on Xenial with tzdata 2016c-1.

This seems to indicate a leap second may have been introduced in this new tzdata, not sure what we can do about this.

After looking at the changelog for the tzdata package, it may have more to do with the version of python / dateutils.
