But a day on Earth >(and on Mars and Pluto) will always be a synodic (mean solar) day, >whatever decision is made at WRC-15. You are wrong in both claims. The fundamental problem in POSIX is the value of the integer 'time_t' not in how it is represented in human form. POSIX is therefore perfectly capable of handling any calendarial form of time you care for, *including* UTC with leap-seconds, (with the footnote that a few seconds suffer from an ambiguity of the same kind as the "repeat-hour" during DST switchback). On much of the planet, "a day" is not a "synodic (mean solar) day" twice a year, when DST is started/stopped, and for any person travelling from one timezone to another, the concept "day" has nothing at all to do with the mean solar day. So "always" ? not even close... -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
