title: Display week day in i3 status bar
body: <p>I want to display the current week day (e. g. Monday) in the i3 status bar.</p>
  
  <p>My current status bar has the following format:<code>27.06.2016 18:00:00</code>.
  I want to achieve a format like this: <code>Monday, 27.06.2016 18:00:00</code>.</p>
  
  <p>The corresponding config in i3status.conf looks like this: </p>
  
  <pre><code>tztime local {
      format = "%d.%m.%Y %H:%M:%S"
  }
  </code></pre>
  
  <p>I am running i3 on a Debian Linux.</p>
  
  <p>Does anybody have a solution on how to display the week day in the status bar? The man page offers no solution, neither did an internet search...</p>
