title: Date attribute format Weka
body: <p>I have imported an Arff file structured in this way:</p>
  
  <pre><code>@relation pv_italy 
  @attribute idsito numeric 
  @attribute data date "yyyy-MM-dd HH:mm:ss" 
  @attribute id.x numeric 
  @attribute anno numeric 
  @data 
  1,"2012-01-01 02:00:00",1,2012
  </code></pre>
  
  <p>After that I imported the file, in "Selected Attribute" panel the "date" attribute isn't in the form "yyyy-MM-dd HH:mm:ss" but in milliseconds. 
  I use Weka 3.9.1.
  I would know how should i do to visualize the date in the format that i defined in the arff file.</p>
  
  <p>Cheers</p>
