change mtime of directory under windows

[Marcus Stojek]

Hi,
can anybody tell me please how to change mtime and/or atime for
a directory under windows.

os.utime(dir,(mtime,atime)) doesn't work (Permission denied)
win32file.SetFileTime(dir,mtime) doesn't work either, because dir is
no file handle

I didn't find anything useful.

Thanks,
marcus
