I agree with Pavel. Japan also may be adapting daylight savings time sooner or later, so it might be a good idea to work on timezone-related problems in core Ruby soon. Updates of timezone information doesn't have to be frequent, for most purposes (work in a locality that doesn't change timezone rules), even no update is okay. To keep current for timezones world-wide, an update about once a month should be more than enough; governments change timezone rules at their will, but do it well in advance. In general, it is difficult if not impossible to provide a time class that satisfies everybody from business people to astronomers and historians (and is still easy to use by programmers). But we should be open to improvements. Regards, Martin.
