<code>set-file-times</code> sets both the access time and modification time of the file. Time values are in the usual Emacs list form. |
|||
Emacs file name handler magic applies to both <code>file-attributes</code> and <code>set-file-times</code> so they can act on "remote" files too. |
|||
File visiting buffers record the modification time of the file so as to guard against changes by another program. <code>set-file-times</code> from within Emacs doesn't update those buffer times and so looks like an external change. |
