title: changing timestamp in logstash 1.4.1
body: <p>I am using logstash 1.4.1 with the following config :</p>
  
  <pre><code>input {
      stdin {    
      }
  }    
  output {
      stdout {}
  }
  </code></pre>
  
  <p>When I launch the agent and then type "hello" in the console, I get this:</p>
  
  <pre><code>2014-05-30T15:02:24.301 +0000 HOSTNAME hello
  </code></pre>
  
  <p>I would like to add 2 hours to the timestamp (I am a french user), and so get this :</p>
  
  <pre><code>2014-05-30T17:02:24.301 +0000 HOSTNAME hello
  </code></pre>
  
  <p>In an older version, I was adding this filter to my config :</p>
  
  <pre><code>filter {
      ruby {
          code =&gt; "event['@timestamp'] = event['@timestamp'].localtime('+02:00')"
      }
  }
  </code></pre>
  
  <p>and everything worked well, but I think that since the update to 1.4.1 the filter has no impact.</p>
  
  <p>Is anyone is having the same problem or find a solution?</p>
