title: MySQL 5.6 DATETIME doesn't accept milliseconds/microseconds
body: <p>Running MySQL 5.6.7-rc which allegedly supports <a href="http://dev.mysql.com/doc/refman/5.6/en/fractional-seconds.html">fractional seconds in time values</a>. Right...</p>
  
  <p>Try this in MySQL Workbench 5.2.44:</p>
  
  <pre><code>CREATE TABLE T (dt DATETIME);
  INSERT INTO T (dt) VALUES ('2012-11-12 13:54:00.123');
  SELECT dt FROM T;
  </code></pre>
  
  <p>The output is this:</p>
  
  <pre><code>2012-11-12 13:54:00
  </code></pre>
  
  <p><strong>What am I missing here?</strong></p>
