title: Updating year in datetime variable
body: <p>I'm playing around with manipulating a <code>datetime</code> variable. I can't seem to find a way to update a <code>datetime</code> variable year to the current year.</p>
  
  <p>For example I have </p>
  
  <pre><code>2007-12-01 00:00:00.000
  </code></pre>
  
  <p>But I would like that to be </p>
  
  <pre><code>2012-12-01 00:00:00.000    (The current year were in)
  </code></pre>
  
  <p>I've been playing with <code>datediff</code>, but I can't seem to nail it.</p>
  
  <p>Any advice would be appreciated.</p>
  
  <p>Thanks </p>
