title: PHP: strototime last Sunday at 8 PM
body: <p>I need to get the Unix time stamp of the last sunday at 8 pm, so I tried:</p>
  
  <pre><code>strtotime("last sunday 8 pm");
  </code></pre>
  
  <p>This works great, but if it is <code>22-11-2015</code> at 9 PM for instance, the output is <code>15-11-2015 8 PM</code> instead of one hour ago. The method above works great except during the last four hours of sunday. How can I get <code>22-11-2015 8 PM</code>?</p>
