for utimes - change the call to ntimes. This preserves nsec timestamps we get from stat (if the system supports it) and only maps back down to usec or sec resolution on time set. Looks bigger than it is as I had to move lots of internal code from using time_t and struct utimebuf to struct timespec. Jeremy.
