[New-bugs-announce] [issue43649] time.strftime('%z') doesn't return UTC offset in the form ±HHMM

New submission from Patrick Storz <Eduard.Braun2 at gmx.de>:

This is a follow-up to https://bugs.python.org/issue20010

I'm seeing this very issue in a recent gcc build of Python 3.8 (mingw-w64-x86_64-python 3.8.8-2 from MSYS2 project):

Python 3.8.8 (default, Feb 20 2021, 07:16:03)  [GCC 10.2.0 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> time.strftime('%z', time.localtime(time.time()))
'Mitteleuropäische Sommerzeit'
>>> time.strftime('%Z', time.localtime(time.time()))
'Mitteleuropäische Sommerzeit'


If this is indeed fixed in MSVCRT, it seems behavior is still not guaranteed when compiling with mingw-w64 gcc.
