I would then have to write up a program for that. We should not duplicate the work done externally in tracking timezone changes, nor embed copies of such frequently changing data in glibc (the existing copies of timezone data are purely for use as test inputs for zic and time-related functions, not for installation). I don't think it's useful to embed Olson timezone names in glibc locales either. Rather, location-selection mechanisms maintained entirely outside glibc should provide user-friendly ways of choosing both (language, country) locale rules and timezone (the latter might change when travelling, the former probably not). Olson timezone names are explicitly not intended to be presented directly to users for timezone selection. See the Theory file . If a distribution is presenting such names (and thus causing issues because the named city is politically inappropriate), report it as a bug directly to that distribution. -- Joseph S.
