This is what it does now, only it only does it for the next year, then assumes the result applies to every year. As I said before, I will try making it do this for every year when needed. Extracting the information directly from the tz database (which must contain it, in some format) would require less CPU, but more of my CPU to figure out how to do it (especially in a system-portable way). _______________________________________________ emacs-pretest-bug mailing list emacs-pretest-bug@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug
