title: Make Logback include the "T" between date and time in its "%date" format for strict ISO 8601 compliance
body: <p>By default, the <a href="http://logback.qos.ch/">Logback</a> encoder uses a <a href="http://logback.qos.ch/manual/layouts.html#date">date format</a> similar to the <a href="http://en.wikipedia.org/wiki/ISO_8601">ISO 8601</a> standard. But it lacks the "T" in the middle between the date and time portions. The <code>T</code> makes for easier parsing, and is required by the standard (unless private parties agree otherwise).</p>
  
  <p>Is there some trick to <strong>get Logback to include the <code>T</code></strong>? </p>
  
  <p>This…</p>
  
  <pre class="lang-none prettyprint-override"><code>2006-10-20T14:06:49,812
  </code></pre>
  
  <p>instead of this…</p>
  
  <pre class="lang-none prettyprint-override"><code>2006-10-20 14:06:49,812
  </code></pre>
  
  <p>I suppose I could re-create the entire format while adding a "T", but I wonder if there is some simpler way.</p>
