You seem to have the meaning of "ignore leap seconds" backwards. POSIX timestamps are not *literally* seconds since the epoch. They are *non-leap* seconds since the epoch, which is just what you want. IOW the simple calculation ignoring leap seconds (found e.g. in calendar.py) will always produce the right value. -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
