title: Display current date and time without punctuation
body: <p>For example, I want to display current date and time as the following format:</p>
  
  <pre><code>yyyymmddhhmmss 
  </code></pre>
  
  <p>How do I do that? It seems like most date format comes with <code>-</code>, <code>/</code>, <code>:</code>, etc.</p>
