Can one AngularJS controller call another?

Is it possible to have one controller use another?

For example:

This HTML document simply prints a message delivered by the MessageCtrl controller in the messageCtrl.js file.

<html xmlns:ng="http://angularjs.org/">
<head>
    <meta charset="utf-8" />
    <title>Inter Controller Communication</title>
</head>
<body>
    <div ng:controller="MessageCtrl">
        <p>{{message}}</p>
    </div>

    <!-- Angular Scripts -->
    <script src="http://code.angularjs.org/angular-0.9.19.js" ng:autobind></script>
    <script src="js/messageCtrl.js" type="text/javascript"></script>
</body>
</html>

The controller file contains the following code:

function MessageCtrl()
{
    this.message = function() { 
        return "The current date is: " + new Date().toString(); 
    };
}

Which simply prints the current date;

If I were to add another controller, DateCtrl which handed the date in a specific format back to MessageCtrl, how would one go about doing this? The DI framework seems to be concerned with XmlHttpRequests and accessing services.
