title: Emacs org-mode, exporting to HTML: CLOSED timestamps?
body: <p>When exporting Org-mode content like this to HTML (i.e. C-c C-e h h)...</p>
  
  <pre><code>* Some project
  ** DONE Some final work
     CLOSED: [2016-03-30 Wed]
     Received final report blah blah...
  ** DONE Final tests
     CLOSED: [2016-03-28 Mon]
  ...
  </code></pre>
  
  <p>...the CLOSED timestamps are not shown in the HTML output. To see if I can see exported timestamps at all, I manually went and changed the DONE entry to this:</p>
  
  <pre><code>* Some project
  ** DONE Some final work [2016-03-30 Wed]
     CLOSED: [2016-03-30 Wed]
     Received final report blah blah...
  </code></pre>
  
  <p>...and then the timestamp does indeed show, in the HTML TOC output (in light gray). </p>
  
  <p>Even though I can use my editing foo to do this automatically, I'd rather not, if I can avoid it. Is there a way to force CLOSED timestamps to show in the Org-mode exported HTML output?</p>
