Those local rules are the rules. The IANA tz community is the place where the folks who track the history and ongoing changes to those rules do their best-effort collaboration, and the rest of the world who rely on tz owe them deep gratitude for taking the trouble to do so. IMHO, the tz community has adopted a viewpoint which is pretty much that timezones are whatever the people who live somewhere do to their clocks, and sometimes that is contrary to the existing legal framework, but even if so that still qualifies as a timezone. Getting back to the topic of this list (leap seconds and UTC), in the proceedings of the two Future of UTC conferences http://futureofutc.org/ there are several papers taking closer looks at the legal basis by which those timezones are based on GMT or UTC. Again, in many places it is not clear whether the law chooses between those two. Aside from that, my impression is that most of this query is better answered in the context of the tz mail list than by LEAPSECS. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
