If @var{time} is address@hidden, then this function gives the new file
the same last-modified time that the old one has. (This works on only
some operating systems.) If setting the time gets an error,
address@hidden signals a @code{file-date-error} error.

+If argument @var{preserve-uid-gid} is @code{nil}, we let the operating
+system decide the user and group ownership of the new file (this is

address@hidden, we attempt to copy the user and group ownership of the
+file. This works only on some operating systems, and only if you have
