In that is the nugget of how leap seconds are no different announcements that the daylight/summer time zones transition will happen at some date other than the previous schedule. (e.g., due to some sports event like the 2000 Olypmics and the 2006 Commonwealth Games in Australia, or any of the other excuses that bureaucrats have used when they say you'll have to update your zoneinfo files.) Leap seconds are just conventional adjustments (to an underlying presumed-adequately-uniform time scale) which are decreed by human authorities to be implemented at times which are deemed most convenient. They are entirely compatible with the POSIX rules as implemented by the zoneinfo scheme. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory Natural Sciences II, Room 165 Lat +36.99855 University of California 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
