anything from IERS must be public domain, isn't it? How is it not?
The IERS version lacks a copyright notice, and it’s not clear who holds the copyright or under what terms TZDB could legally reproduce the file. The copyright holder might be the IERS, the Paris Observatory, Paris Sciences et Lettres University, the Ministry of National Education, or some other body. A while ago I asked for a proper copyright notice to be added, to clarify rights and establish permissions, but this has not gotten anywhere presumably because the people in charge of the IERS version are busy and don’t think this is important.
They are part of an international org in an EU org and may still be waiting for approval of the document specifying the application of the copyright, data, and database rights to the file and its data. ;^> [I read about one bureaucrat who had spent seven years thus far trying to get a document approved!] -- Take care.
