title: JavaScript - seconds to readable format?
body: <p>I've got a variable with a number such as <code>1,235,752,564,445,799,865,346</code> - how can I turn this into a readable formate such as instead of that large number, display it as <code>4 quadrillion centuries</code>, or to the actual equivalent?</p>
  
  <p>So, for example <code>29030400000</code> seconds would be displayed as <code>1 millennium</code>?</p>
