 .. function:: utime(path, times)
 
-   Set the access and modified times of the file specified by *path*. If *times* is
-   ``None``, then the file's access and modified times are set to the current time.
-   Otherwise, *times* must be a 2-tuple of numbers, of the form ``(atime, mtime)``
-   which is used to set the access and modified times, respectively. Whether a
-   directory can be given for *path* depends on whether the operating system
-   implements directories as files (for example, Windows does not).  Note that the
-   exact times you set here may not be returned by a subsequent :func:`stat` call,
-   depending on the resolution with which your operating system records access and
-   modification times; see :func:`stat`.
