Explanation / Answer

Your HTML is not visible..So i can't test..But u can try the below code..I think it will work..

function updateDuration()

{ 'use strict';

// Get now:

var now = new Date(); // Create the message:

var message = 'It has been ' + now.getTime();

message += ' seconds since the epoch. (mouseover to update)'; // Update the page:

U.setText('output', message); }

// End of updateDuration() function.

// Establish functionality on window load:

document.$ready(function()

{ 'use strict';

// Create the event listener:

U.addEvent(U.$('output'), 'mouseover', updateDuration);

// Call the function now:

updateDuration();

};);
