Why use zone names at all?

What we refer to as "timezones" are often strictly speaking two different
(A) A fixed offset relative to UTC (e.g., in Germany MEZ = +0100
and MESZ = +0200)
(B) A rule that determines the offset to UTC (e.g., in Germany
MEZ is +0100 in winter and +0200 between the last Sunday of
March and October, with a switch at 02:00 or 03:00).
For (A), I agree that a numeric designation a la ISO 8601 is
clearly the best solution. However, you will still need names in
order to identify (B).
What is the exact terminology with regard to (A) and (B). So far,
I have heard the word "timezone" being used inconsistently for both.
