title: Boostrap datetimepicker: startDate: -Infinity not working
body: <p>I'm working with <a href="http://tarruda.github.io/bootstrap-datetimepicker/" rel="nofollow noreferrer">bootstrap datetimepicker</a> and I want to disabled the past days and I used </p>
  
  <blockquote>
    <p>startDate: -Infinity</p>
  </blockquote>
  
  <p>to set a minimum date but it  doesn't work. And also i received an error in my console.</p>
  
  <blockquote>
    <p>Uncaught TypeError: Cannot read property 'fn' of undefined</p>
  </blockquote>
  
  <p>I also used the working code from this <a href="https://stackoverflow.com/questions/15757918/disable-past-dates-on-datepicker">thread</a> but still not working in my project.
  Here is my code:</p>
  
  <pre><code>   &lt;div id="datetimepicker1" class="input-append date"&gt;
       &lt;input data-format="dd/MM/yyyy" type="text"&gt;&lt;/input&gt;
          &lt;span class="add-on"&gt;
          &lt;i data-time-icon="icon-time" data-date-icon="icon-calendar"&gt;
          &lt;/i&gt;
          &lt;/span&gt;
     &lt;/div&gt;
  </code></pre>
  
  <p>My Javascript:</p>
  
  <pre><code>  $(function(){ 
          $('#datetimepicker1').datetimepicker({ 
          startDate: -Infinity , 
          pickTime: false
      });
    });
  </code></pre>
  
  <p>Regards!</p>
