I don't really think that the presence or absence of enforced penalties for failing to precisely adhere to sunrise/sunset-based restrictions makes any particular argument either for or against any proposal of what to do with leap seconds. The times of sunrise and sunset, after all, are not a constant in any time scale now in use or seriously proposed; they vary by latitude, longitude, time of year, variance from year to year due to the leap-year cycle, and are affected by any change in length of day, length of year, and tilt of Earth axis. Astronomers have to do whatever complex calculations they need to do in order to figure them out to the desired accuracy, and any vagaries of the civil time system such as the presence or absence of leap seconds (along with time zones and daylight saving time) are just some more things needing to be taken into account. Everybody else just reads the results in an almanac. -- == Dan == Dan's Mail Format Site: http://mailformat.dan.info/ Dan's Web Tips: http://webtips.dan.info/ Dan's Domain Site: http://domains.dan.info/ _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
