That interesting but wasn't really my question. What I was asking, regardless of the semantics of meta vs direct, was whether it would be theoretically workable (in a vacuum presuming everyone can be upgraded to a new tzdb [with winter negative "saving" and summer zero offset standard] concurrently with a version of CLDR data with such a change) for the CLDR to regard a "GMT" with a negative offset as <daylight> and IST as <standard>, even if that would mean it couldn't inherit the translations of "Greenwich Mean Time" from the British zone?
