body: <p>How to get the current time in millisecond in MySQL.</p>
  
  <p>So far what I've got is <code>UNIX_TIMESTAMP()</code>.</p>
  
  <p><strong>But it returns the current time in seconds.</strong></p>
  
  <p>But I want the current time in <strong>milliseconds</strong> in UTC since '1970-01-01 00:00:00'   in MySQL.</p>
  
  <p><em>Any suggestion?</em></p>
