title: Change the sysdate value?
body: <p>Before I start, I don't speak English very well, so I apologize for any mistakes.</p>
  
  <p>I want to change the <code>sysdate</code> value because it is different to the date value of the system. When I execute <code>"SELECT sysdate FROM dual"</code>, I get an hour "X", but when I get the date from the system (in the console, I type "date"), I get the date "X" but -12 hours, ex: </p>
  
  <pre><code>*Query executed on Toad: SELECT to_char(sysdate, 'dd/mm/yyyy hh24:mi:ss') FROM dual;
  
                          -&gt; 09/04/2014 05:18:30
  
   *In Linux Server shell: date
  
                          -&gt; Tue Apr  8 17:19:17 CDT 2014
  </code></pre>
  
  <p>What's wrong? I've restarted all instances including the listener, we handle grid infrastructure to our DB on a linux server.</p>
  
  <p>Can I change the sysdate value?</p>
