title: How to print time as #inst
body: <p>It's easy to read a date literal:</p>
  
  <pre><code>(read-string "#inst \"2012\"")
          ;;; ⇒ #inst "2012-01-01T00:00:00.000-00:00"
  </code></pre>
  
  <p>How can I output a date as a <code>#inst...</code> literal?</p>
  
  <p>This does not work:</p>
  
  <pre><code>(pr-str (clj-time.core/now))
          ;;; ⇒ "#&lt;DateTime 2013-07-09T17:26:30.058Z&gt;"
  
  (read-string (pr-str (clj-time.core/now)))
          ;;; ⇒ &lt;err&gt;
          ;;;   RuntimeException Unreadable form  clojure.lang.Util.runtimeException (Util.java:219)
  </code></pre>
