bpo-30822: Fix testing of datetime module. by musically-ut · Pull Request #2783 · python/cpython
I merged the PR. It was already approved and merged in PR #2530. I reverted the first attempt because test_datetime became too slow on some buildbots where the test timed out and so made tests failing.
We agreed on http://bugs.python.org/issue30822#msg297760 to exclude the slow tzdata resource to not test all timezones in test_datetime on buildbots, but only run a few selected timezones.
So I merged this new PR which is just a copy of the first one ;-)
Thank you again @musically-ut, sorry for the mess ;-)
I'm not sure why AppVeyor thinks that this PR is non-mergeable.
No idea.
