title: Create a scheduled Greasemonkey script
body: <p>I need to create a special kind of script.<br>
  I want to show a message at certain times of the day. I've tested the code in Firebug Console and it works. The code is:</p>
  
  <pre><code>//Getting the hour minute and seconds of current time
  var nowHours = new Date().getHours() + '';
  var nowMinutes = new Date().getMinutes() + '';
  var nowSeconds = new Date().getSeconds() + '';
  
  var this_event = nowHours + nowMinutes + nowSeconds;
  //172735 = 4PM 25 Minutes 30 Seconds. Just checked if now is the time
      if (this_event == "162530") {
          window.alert("Its Time!");
      }
  </code></pre>
  
  <p>I feel that the Script is not running every second. For this to work effectively, the script has to be able to check the hour minutes and second "Every Second". I'm not worried about the performance, I just have to be accurate about the timing (to the second).</p>
  
  <p>How do I do this?</p>
