Here's how its done by Fcopy_file():

        {
          EMACS_TIME atime, mtime;
          EMACS_SET_SECS_USECS (atime, st.st_atime, 0);
          EMACS_SET_SECS_USECS (mtime, st.st_mtime, 0);
          if (set_file_times (XSTRING (encoded_newname)->data,
                              atime, mtime))
            Fsignal (Qfile_date_error,
                     Fcons (build_string ("Cannot set file date"),
                            Fcons (newname, Qnil)));
        }

If set_file_times() were exposed to Lisp, then you would be able to use
it in Tramp.  (If anyone does that, it'd be nice if the ATIME and MTIME
arguments were lists, as returned by file-attributes.)
