I'd concur with Paul Eggert and suggest forego building a theory for this. That FT means forward time was emailed to the tz-list, this act could be regarded as theory building. But I wouldn't regard writing the theory down as building one.
Since it was you who proposed that FT means forward time, did you with your last email intend to withdraw your proposal?
This is a clear once-only case, and should be discussed as such, I think. I am one of those that cannot predict the future.
If one writes the meaning into the Theory file, it can be marked there as currently only used by EEFT, but the the next time such a situation of "forward time" occurs people can find it. Some people may have all the theory in their head, but there it is in danger of getting changed without notice. If the theories behind the tz database are written down into the Theory file, at least other people can check the theories and find any changes by using diff tools. My reworded proposal for the Theory file is: -------- All abbreviations end in "T". Some generic endings are: - MT for mean time (e.g. GMT), - ST for summer time (e.g. BST, CEST), - DST for double summer time (e.g. BDST, MDST) - FT for forward time (permanent summer time, only used for EEFT). The strings are also used in zone abbreviations without having these meanings, e.g. AFT = Afghanistan Time, ALMT = Alma-Ata Time, IST = Indian Standard Time. Zones that use ST to mean standard time commonly use DT to mean daylight [saving] time, e.g. EST, EDT in North America. -------- -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/tobias_conradi
