title: Php time format conversion
body: <p>I have the following timeformat:<code>15/08/2011 12:32:23</code> day/month/year hour:minute:sec and I want to convert to the following format: Y-m-d H:i:s</p>
  
  <p>I tried with <code>date('Y-m-d H:i:s', strtotime($time))</code> but it not works. It swaps the month and the day when it's converting from string to datenum.</p>
