title: Why do a Clojure instant uses a "-" instead of a "+" when describing timezones?
body: <p>Note that in the following Clojure REPL, I input the <code>instant</code> with  "+00:00" or "+01:00" to describe the timezone information but the REPL output produces an <code>instant</code> using "-00:00" (UTC).</p>
  
  <pre><code>user&gt; #inst "2016-11-12T20:33:31.000+00:00"
  #inst "2016-11-12T20:33:31.000-00:00"
  user&gt; #inst "2016-11-12T20:33:31.000+01:00"
  #inst "2016-11-12T19:33:31.000-00:00"
  </code></pre>
  
  <p>Is this behaviour by design?</p>
  
  <p>I'm using Clojure 1.8.0.</p>
