title: How to add a build timestamp at the end of the minified files
body: <p>I have a real issue now, When I'm on Production and when ever I update my CSS or JS the same file keeps on serving from the server.. I i need to get the new updates then I have to hard refresh the browser,</p>
  
  <p>I'm thinking of having a way to add a build version at the end of my minified file name, So when ever my files are updated and Grunt minifies my files it will output a perfect link which will be newly downloaded by the web browser</p>
  
  <p>Right now the link is like this</p>
  
  <pre><code>&lt;script src="/min/production.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I need this to be,</p>
  
  <pre><code>(&lt;script src="/min/production[timestamp].min.js"&gt;&lt;/script&gt;)
  </code></pre>
