title: What type of timestamp does "gcloud compute instances list" produce
body: <p>When you output gcloud compute instances list as json, the timestamps look like this:</p>
  
  <pre><code>2016-05-22T12:22:29.285-07:00
  </code></pre>
  
  <p>But I can't find an explanation of the format in the documentation. I would interpret it as:</p>
  
  <pre><code>YYYY-MM-DDT&lt;hours&gt;:&lt;minutes&gt;:&lt;seconds&gt;.&lt;fraction&gt;-&lt;timezone&gt;
  </code></pre>
