title: How to convert HH:MM:SS string to datetime?
body: <p>i am having an input string of HH:MM:SS for example 15:43:13,</p>
  
  <p>now i want to convert it to datetime but keep just the hour/time without the date etc</p>
  
  <p>is it possible?</p>
  
  <p>for example </p>
  
  <pre><code>string userInput = 15:43:13;
  DateTime userInputTime = Convert.ToDateTime(userInput);
  </code></pre>
  
  <p>will give me the full date including the year etc,
  is there any way to convert it to just HH:MM:SS without triming/substring?</p>
  
  <p>thanks</p>
