title: Check if timestamp is today
body: <p>I've got a timestamp in the following format (Which can easily be changed thanks to the beauties of PHP!).</p>
  
  <blockquote>
    <p>2011-02-12 14:44:00</p>
  </blockquote>
  
  <p>What is the quickest/simplest way to check if this timestamp was taken today?</p>
