     <p>It also outputs <code>msg.start</code>, <code>msg.end</code> and <code>msg.now</code> which are todays start and end times, with offsets applied, in ISO format, and the current ISO time.</p>
     <p><code>msg.sun</code> is an object containing the azimuth and altitude, in degrees, of the current sun position.</p>
