Simon> Emacs 20.7, 21.1 (and XEmacs 21.4 with patch): Simon> (encode-time 0 0 1 1 1 1969 nil nil 3600) Simon> (-482 52352) This result is plausible, but the C standard does not require GNU's make_time to produce it AFAIK. For XEmacs 21.4.6, I'm going to (1) use GNU's make_time(), but divide by 2^16 when time is negative to guarantee the desired result (how Martinesque), and (2) eliminate use of (wasteful_)?word_to_lisp() to decode time (only in dired.c). Comments? Simon's patch follows in full for those who just joined us. The semantic difference between Simon's version and the current XEmacs code can be summarized by "s/time_t/unsigned int/". 2001-11-10 Simon Josefsson <jas(a)extundo.com&gt; * editfns.c (make_time): New function, from Emacs.
