title: Ruby Datetime parse error with different format
body: <p>I want to convert string to DateTime object which is in different format "13:54 25/02/2016", Is there any way to do this?</p>
  
  <p>I've tried different ways, but getting error. I'm using ruby version '2.1.2'</p>
  
  <p>Example:</p>
  
  <pre><code>DateTime.parse("13:54 25/02/2016") # ArgumentError: invalid date
  DateTime.strptime("13:54 25/02/2016") ArgumentError: invalid date
  </code></pre>
