title: Vue.js: console warning with vue-moment with firebase dates from authentication - date updated
body: <p><strong>Moment is returning what I want...</strong></p>
  
  <p><code>Date updated: 41 minutes ago</code></p>
  
  <p>But I get Chrome console warning:
  <code>Could not build a valid `moment` object from input.</code></p>
  
  <hr>
  
  <p><strong>Date coming from Firebase in this format</strong></p>
  
  <p>dateUpdate:</p>
  
  <p><code>2018-10-25T17:33:24.537Z</code></p>
  
  <p><strong>profile.vue</strong></p>
  
  <pre><code>&lt;span&gt;Date updated: {{ dateUpdated | moment("from", "now") }}&lt;/span&gt;
  </code></pre>
  
  <p><strong>Question</strong>
  How do I suppress this error?  </p>
  
  <p>(it seems that the Firebase date is not valid for moment.js)</p>
  
  <p><strong>vue-moment.js</strong></p>
  
  <pre><code>  if (!input || !date.isValid()) {
      // Log a warning if moment couldn't reconcile the input. Better than throwing an error?
      console.warn('Could not build a valid `moment` object from input.');
      return input;
    }
  </code></pre>
  
  <p>Thanks,</p>
