CLDR does not determine offsets. CLDR just maintains an array of names by category. In CLDR, we define several different type of names for a zone (and localized names in various locales) -
1. Long standard (e.g. Pacific Standard Time) 2. Long daylight (e.g. Pacific Daylight Time) 3. Long generic (e.g. Pacific Time) 4. Short standard (e.g. PST) 5. Short daylight (e.g. PDT) 6. Short generic (e.g. PT)
What about the name for the third offset each year? The UK used to use three offsets during the year. I'm sure it was not alone. I'm certainly not sure that it won't happen again.
What if the same offset has different names in different contexts? A majority-Muslim country that puts its clocks back for Ramadan (I believe such exist) might use the names XXX Winter Time, XXX Summer Time, and XXX Ramadan Time, the last to make it clear that it's not because of winter.
If your answer is "we'll deal with that when it happens" then, well, it's happened.
At least Egypt and Morrocco have done this since 1990 (the arbitrary time before which CLDR considers irrelevant by policy). Trivial to find sources: https://en.wikipedia.org/wiki/Daylight_saving_time_in_Egypt https://en.wikipedia.org/wiki/Daylight_saving_time_in_Morocco Winter is hardly an appropriate description for these times of the year in those countries. (In fact, the whole rationale for messing with time like this is because summer overlapping with Ramadan presents certain challenges).
