title: How to determine when chef last converged on a node?
body: <p>I am using Chef <code>11.12.4</code>. For a given node, I would like to know when it last converged. I found <a href="http://jtimberman.housepub.org/blog/2013/02/16/last-check-in-time-for-nodes/" rel="nofollow">a blog post</a> about finding <code>ohai_time</code>, but it's not clear to me that it's necessarily the same value as last converge time.</p>
  
  <p>The reason I want to know this is because I uploaded a new cookbook version, but I'm not seeing the change taking affect on my nodes. I want to know if converge is not running, or if converge has run, but my cookbook contained an error.</p>
  
  <p>It would also be nice to know what the status of the last converge was.</p>
  
  <p>I'm hoping for something like this:</p>
  
  <pre><code>$ knife node converge-status my-node-name
  my-node-name successfully converged at 1:23:45 UTC.
  </code></pre>
  
  <p>Does this exist?</p>
