We are not in agreement on this point.

CLDR translates principal city names affiliated with timezones, and
provides a mapping to Windows timezones.  That is all.

(It doesn't define or translate timezone names, or allow for the
grouping of historical timezones in to a reduced set of entitites
suitable for presentation to end users.)

It's easy to find internationalised geoname data... one approach might
be to look at language equivalence across the Wikipedia dataset,
another OpenStreetmaps, etc.
