I thought consistency within module trumps PEP 8 naming standards.
The datetime module (for better or worse) uses lowercase names for its
types: date, time, datetime, tzinfo.  Shouldn't the new type follow
the suit? (This will also avoid a source of typos TimeZone vs.

I don't like "fixed timezone" - it is not clear what it is fixed:
offset, geographical location or historical set of rules.  I think we
should promote the notion that timezone is just an offset.  EST is -5
hours, EDT is -4.  New York uses EST in winter and EDT in summer.   A
zoneinfo database (external to python) is a mapping from place and
time to timezone.
