CURRENT: No private use area defined. PROPOSAL: Define a private use area. Use AA or Aa to have the name start with the same letter as most other Areas that represent continents do (America, Africa, Asia, Australia) Since AA is an ISO 3166-1 alpha-2 private code, it can be used by CLDR, that uses UN/LOCODEs, too, to define a private range. The private range would be defined on the top level, so it is not affected by any change to the Area names (America, Africa, Asia, Australia, etc.) Organizations are then free to have their own subareas inside, e.g. i Aa/NorwayGov/Bouvet/ Aa/RussiaGov/Barnaul/ Aa/GemBuesingen/Buesingen/ Aa/Pre1970project/ Aa/JohnDoe/ Aa/Legal/ (legal time instead of majority observed time) REASONING: Allow people to create zones having names that will not be the same as IANA time zone names. This is helpful when the IANA time zone database maintainers do not fix bugs (e.g. West Siberia) and do not create zones for regions solely because they have no permanent population, despite the time there being defined by law of the sovereign state to which it belongs (Bouvet Island). == Systems having a private use area == === Country codes === ISO 3166-1 alpha-2 AA, QM ...
