Fails locally but passes in CI on the same commit. Its because the test fixture includes tzlocal(), and for some timezones (incl most of europe), one of the testcases spans a DST transition:
date_range(start='2014-08-01', end='2014-10-31', freq='T')
Expected Output
should pass, regardless of the local timezone
