title: how to change time column in HTML layout of Log4j2
body: <p>For my application I need HTML layout for logging events.The time in time column appears in milli seconds but I need it in dd-MM-yyyy:HH:mm:ss.sssZ format.
  How do I do that?
  Because HTML layout of log4j2 does not support pattern attribute. So I'm not able to set new pattern for time.</p>
