  A quick fix for my friend Chris Bowler.

<link rel="stylesheet" media="screen" id="time_style" href="/-/css/day.css" />
<script>
(function() {
  var currentTime = new Date().getHours();

  if (currentTime < 7 || currentTime > 20) {
    document.getElementById('time_style').href = '/-/css/night.css';
  }
})();
</script>

This way, there's at least a default present, and you override it only if it's night time :)
