For time-stamps, the best thing to use is a simple count of TAI seconds, same as the Perl 6 core (S02) Instant type. Save representing dates as YMDHIS for user-entered artifacts. You can also convert the TAI to a YMDHIS for user display when necessary, but otherwise that extra complexity isn't needed. AFAIK, TAI can be determined in the first place simply as an offset from the Unix integer time, I think. Various Perl modules exist to help; search for TAI on CPAN. -- Darren Duncan _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
