title: Node with Mysql2 timezone issue
body: <p><strong>When I am trying to set the timezone with mysql2 getting the bellow message.</strong>
  <strong>With MySQL working fine.</strong></p>
  <p><strong>But I have to use mysql2 only</strong></p>
  <pre><code>var mysql2 = require('mysql2');
  
  var con = mysql2.createPool({  
  connectionLimit : 10, 
  host: process.env.DATABASE_HOST, 
  user: process.env.DATABASE_USER,  
  password: process.env.DATABASE_PASSWORD,  
  database : process.env.DATABASE_NAME,  
  timezone : 'IST'      
  })
  </code></pre>
  <p><strong>Problem</strong></p>
  <blockquote>
  <p>Ignoring invalid timezone passed to Connection: IST. This is currently
  a warning, but in future versions of MySQL2, an error will be thrown
  if you give an invalid configuration option to a Connection</p>
