title: sas adding 7 days to a date
body: <p>I would need to add to a date format variable 7 days.</p>
  
  <p>The variable is creation_date and is like <code>01JAN14:00:08:04</code>.</p>
  
  <p>I wrote this in a data step</p>
  
  <pre><code>sevendays_after=CREATION_DATE+ 7 * 24 * 60 * 60;
  </code></pre>
  
  <p>but the result is like <code>1.70476E9</code></p>
  
  <p>and I need it like <code>08JAN14:00:08:04</code>. </p>
  
  <p>Also I would need to keep only the yymmdd  or ddmmmyy and I don't know how to do this either.</p>
  
  <p>Thanks!</p>
