Addclass for period of time on Jquery
<p>I have a following HTML</p>

<pre><code>&lt;div id="btn_1"&gt;Button 1&lt;/div&gt;
&lt;div id="btn_2"&gt;Button 1&lt;/div&gt;
&lt;div id="btn_3"&gt;Button 1&lt;/div&gt;
</code></pre>

<p>I want add a css class for period of time, for example: If the hour is between 00:00 to 06:59  add class "select" to id "btn_1", for between 07:00 to 10:59 am add the class to id "btn_2", and finally 11:00 to 16:00 add class to id "btn_3".</p>

<p>Any help please?</p>
