title: How to get the age of someones account? Discord.py
body: <p>To prevent new accounts from using a certain command, how could I get the age of a users account (or creation date) when they type a message.</p>
  
  <pre><code>
  client.get_user(account_date)
  
  if account_date &lt; 14:
     print('Your account must be older than 14 days to use this command')
  else:
     print('Your account can use this command')
  </code></pre>
