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.

New submission from Lennart Regebro:
When calling tzname() on a timezone object it will return "UTC" + the offset.
>>> from datetime import timezone, timedelta, datetime
>>> tz = timezone(timedelta(hours=3))
>>> dt = datetime(2013, 3, 14, 12, 30, tzinfo=tz)
>>> dt.tzname()
'UTC+03:00'
But this
