title: Change image based on time of day
body: <p>I want to change the image based on the clock. One picture of day and one picture of night. Between the hours of 06:30 to 18:30 is day (shows a picture of daylight). Between the hours of 18:31 to 06:29 is night (shows a picture of the night). </p>
  
  <p>So two images (lets call them day1 and night1) and two time zones.<br>
  day1 = 06:30 - 18:30<br>
  night1 = 18:31 - 06:29</p>
  
  <p>I'm a newbie when it comes to programming. I want to use this to show my child when it's day and when it's night (or when it's okay to get up in the morning and when it's not).</p>
  
  <p>I guess the best is to use Java. I would have preferred a full screen software. Can someone help?</p>
