title: strtotime minus hours and minutes
body: <p>I have this code:</p>
  
  <pre><code>&lt;?php 
      $date = date('Y-m-d H:i:s', strtotime('-6 hours', (int)get_the_time('U'))); 
      echo $date; 
  ?&gt;
  </code></pre>
  
  <p>as you can see the time is changed by subtracting 6 hours from the time, what I want to subtract the hours and also minutes so I tried this:</p>
  
  <pre><code>&lt;?php 
      $date = date('Y-m-d H:i:s', strtotime('-6 hours', '-23 minutes', (int)get_the_time('U'))); 
      echo $date; 
  ?&gt;
  </code></pre>
  
  <p>But isn't working, any idea?</p>
  
  <p>Thank you in advance</p>
