title: How to change ctime to normal string representation?
body: <p>Using <a href="http://perldoc.perl.org/File/stat.html" rel="nofollow noreferrer"><code>File::stat</code></a> we can get the <code>ctime</code> of a given file. My question is how to change the <code>ctime</code>, which means the inode change time in seconds since the epoch, to a normal  time representation like "2009-08-26 17:28:28". Is there any build-in or module can solve this task?</p>
