New submission from STINNER Victor: A leap second will be added in June 2015: http://www.usatoday.com/story/tech/2015/01/08/computer-chaos-feares/21433363/
The datetime module explicitly doesn't support leap seconds: https://docs.python.org/dev/library/datetime.html#datetime.date.fromtimestamp "Note that on non-POSIX systems that include leap seconds in their notion of a timestamp, leap seconds are ignored by fromtimestamp()." The following bug in oslo.utils was reported because datetime is indirectly used to unserialize a date, but it fails with ValueError("second must be in 0..59") if the second is 60: https://bugs.launchpad.net/oslo.utils/+bug/1427212 Would it be possible to silently drop ignore leap seconds in datetime.datetime constructor, as already done in datetime.datetime.fromtimestamp? Attached patch modified datetime constructor to drop leap seconds: replace second=60 with second=59. I also changed the error message for second (valid range is now 0..60). ---------- components: Library (Lib) messages: 237142 nosy: belopolsky, haypo priority: normal severity: normal status: open title: datetime: support leap seconds versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23574> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
