Gwillim Law / Do not change established names unless they become ambiguous or shockingly incorrect. Yes, but established by whom?
When I said "established names", I was referring to the names that currently exist in the tz archive. They are "established" because people all over the world have downloaded them, which, in turn, is the reason I would like to avoid changing them.
And what would you call shockingly incorrect?
"Shockingly incorrect" was intentionally left undefined. The purpose of that phrase is to allow the maintainers of the tz archive to decline to change a zone name in most circumstances without doing a survey of world literature to justify the decision. Not that I expect my phrasing to be adopted verbatim, of course. It's just a suggestion. Yours, Gwillim Law
