title: HTML Form Input datetime-local include seconds in the input?
body: <p>I can not for the life of me find where to add seconds to an input box for datetime-local</p>
  
  <p>Right now it asks for <code>M-D-Y H:M A/P</code>, I want to add <code>:S</code> to the <code>H:M</code> part. The result would be: <code>M-D-Y H:M:S A/P</code></p>
  
  <p>I'm coding with PHP / HTML5</p>
  
  <p>Any direction would be greatly appreciated.</p>
