New submission from Peter J C Law: There's a difference in behaviour between the ``fromutc`` method on a tzinfo between Python 2 and Python 3, though only under the specific case of Summer Time in regions whose usual offset is 0.
>From what I can tell, it's the Python 3 one which is wrong, based on it no >longer matching the sample implementation provided in the docs and on it >appearing to report the wrong times for ``datetime.now(tz)`` when on a machine >configured for BST during June 2015. Similar results can also be achieved using a manually constructed ``datetime`` for dates during summer 2014. I've put the python script (and sample outputs) I used to investigate in a gist at https://gist.github.com/PeterJCLaw/d8bcc168d68acf066811#file-time_issues-py. The outputs there are for pythons 2.7.9 and 3.4.0. ---------- components: Library (Lib) messages: 237407 nosy: peterjclaw priority: normal severity: normal status: open title: tizinfo.fromutc changed for tzinfo wih StdOffset=0, DstOffset=1 type: behavior versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23600> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
