title: LUA get date time in format YYYYMMDDHHMMSS
body: <p>I was wondering how to go around getting a date string in the following format:</p>
  
  <pre><code>date = os.date() -- 11/29/18 09:14:04
  </code></pre>
  
  <p>Into the format of YYYYMMDDHHMMSS, so in this example, I would want to return</p>
  
  <pre><code>20181129091404
  </code></pre>
