I don't know if we care, but some pre-C89 implementations of
sprintf() returned a char* (a copy of the first argument, IIRC)
rather than the count of bytes written.  If portability to
such archaic systems is considered to be worth the bother then
this code fragment should read:
    	(void)sprintf(result,
    		ASCTIME_FMT,
    		wn, mn,
    		timeptr->tm_mday, timeptr->tm_hour,
    		timeptr->tm_min, timeptr->tm_sec);
    	pt = result + strlen(result);
