[issue17486] datetime.timezone returns the wrong tzname()

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

This is not a bug in datetime.timezone.  The value returned by timezone.tzname() is documented and the code works correctly.  %Z should not be used to produce machine-readable timestamps and for a human reader 'UTC+03:00+0300' should not be confusing.

Note that calling the astimezone() method (without arguments) will return local time with tzname set:

>>> os.putenv('TZ', 'XYZ-3')
>>> time.tzset()
>>> utctime = datetime.datetime.now(datetime.timezone.utc)
>>> localtime = utctime.astimezone()
>>> localtime.strftime('%Z%z')
'XYZ+0300'
