angular.js - 很简单的一个angularjs入门级demo，但是报错了。

本人初学angularjs，在看一本书的《angularjs 权威教程》，第二章有个demo，如下。

这里使用angular版本1.2.29,如果换成1.3.1 会报错。

请问，这是如何造成的呢？应该怎么样调试这个错误呢？

            setInterval(function() {

            updateClock();
      };

    After version 1.3, controllers are no longer found on the window object $controller will no longer look for controllers on window.

    It is recommended that the poster follow up to version 1.4 (version is really important)

    <!doctype html> 
<html ng-app> 
<head> 
    <meta charset="utf-8"> 
    <title>Simple App</title> 
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.7/angular.min.js"></script>
</head>
<body>
    <p ng-controller="MyController">
        <h1>Hello {{clock}}</h1>
    </p>
    
    <script type="text/javascript">
        function MyController($scope, $timeout) {
            $scope.clock = new Date();
            var updateClock = function() {
              $scope.clock = new Date();
            };
            setInterval(function() {
              updateClock();
            }, 1000);
      };
    </script>
</body>
</html>

    Just like this. . Of course you can also write 

    <!doctype html> 
<html ng-app> 
<head> 
    <meta charset="utf-8"> 
    <title>Simple App</title> 
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.7/angular.min.js"></script>
</head>
<body>
    <p ng-controller="MyController">
        <h1>Hello {{updateClock()}}</h1>
    </p>
    
    <script type="text/javascript">
        function MyController($scope, $timeout) {
            $scope.updateClock = function() {
             return new Date();
            };
            setInterval(function() {
              updateClock();
            }, 1000);
      };
    </script>
</body>
</html>
