title: how to get facebook post time by javascript
body: <p>I'm trying to write a chrome extension to collect the post time for each message on Facebook, but when I checked the HTML of Facebook, the code for post time are displayed like:</p>
  <pre><code>&lt;span class=&quot;nc684nl6 l94mrbxd l9j0dhe7 sdhka5h4 ww7X6Q8&quot; style=&quot;order: 16;&quot;&gt;s&lt;/span&gt;
  &lt;span class=&quot;l94mrbxd aenfhxwr myohyog2 b6zbclly l9j0dhe7 sdhka5h4 ww7X6Q8&quot; style=&quot;order: 1;&quot;&gt;u&lt;/span&gt;
  &lt;span class=&quot;t5a262vz aenfhxwr b6zbclly l9j0dhe7 sdhka5h4&quot; style=&quot;order: 24;&quot;&gt;y&lt;/span&gt;
  </code></pre>
  <p>which are the letters out of order.
  How could I reorder them as the displayed time like &quot;18h&quot; &quot;24 May at 11:00&quot;? Or is there better way to get the post time?</p>
