I'd like for Python to provide a portable implementation of strftime instead of just documenting that the version isn't portable.

If someone wants to do that, I suggest to first start with a project on PyPI. It sounds like a tricky project. Date, time, locales and localization are hard problems! ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue13305> _______________________________________
