a tzinfo subclass must implement utcoffset()

[QubeX2]

try:
    utc = datetime.timezone.utc
except:
    # Support Python 2.7
    class UTC(datetime.tzinfo):
        def fromutc(self, dt):
            return dt

        def **utcffset**(self, dt):
            return datetime.timedelta(0)

        def dst(self, dt):
            return None

        def tzname(self, dt):
            return 'UTC'

    utc = UTC()

This method is misspelled, should be utcoffset
