10439	Test suite side-effects cause dateformat tests to fail	Malcolm Tredinnick	Malcolm Tredinnick	"Running the full tests (as of r10008) shows a failure in the dateformat tests. Running various tests in isolation plus the dateformat test does not generate the failure. So this is some kind of test suite unintended side-effect. Seems to happen under every backend.

The failing test reports this

I snarfed that output from [http://buildbot.djangoproject.com/waterfall the buildbot], but I'm seeing the same results locally.

For anybody investigating this: the wintertime/summertime times are set up to cross a daylight savings boundary from 2005 in Copenhagen (we're very tricky when we write our tests for things like that). The results should be (and have been, until recently) independent of the timezone of the machine doing the testing."		closed	Uncategorized	dev		fixed			Accepted	1	0	0	0	0	0
