IANA and the tz database - diverging from Theory
The 2011-05-19 text by E. Lear and P. Eggert at http://tools.ietf.org/html/draft-lear-iana-timezone-database-04 defines an update rule that is different to the ones in the Theory file, it reads: "3. Making Updates to the TZ Database New TZ names (e.g. locations) are only to be created when the scope of the region a name was envisioned to cover is no longer accurate." Also the Terminology section defines only three TZ specific terms, while the Theory file contains several more. Does anyone know why the rules of tz names are changed in the IANA tz text? -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/tobias_conradi

This was part of the IANA drafting and editing process, which is pretty longwinded. Although the wording changed, the intent remained pretty much the same, as far as I can tell.

The word "accurate" only occurs once in the document. Therefore ----------- "3. Making Updates to the TZ Database New TZ names (e.g. locations) are only to be created when the scope of the region a name was envisioned to cover is no longer accurate." ------------ leaves open to guessing what means "accurate". In the Theory file it says "Include at least one location per time zone rule set per country." The word "country" is not even mentioned once in the IANA text.
Although the wording changed, the intent remained pretty much the same, as far as I can tell. Any intent that is included in the text can be obtained from the text. Any other cannot.

Tobias, The Database Coordinator has a pretty free hand. That having been said, I would suggest that this is a rather evolutionary process, and we can always have follow-up work that further codifies Theory, should that be what people want to do. Eliot On 9/25/11 3:32 PM, Tobias Conradi wrote:
