I don't think that the other posted answers are quite right, you have already accepted one as working for you so I won't edit it.

Here is an updated version of your accepted answer.

var dateString = /Date(1334514600000)/.substr(6);

var currentTime = new Date(parseInt(dateString ));

var month = currentTime.getMonth() + 1;

var day = currentTime.getDate();

var year = currentTime.getFullYear();

var date = day + / + month + / + year;

alert(date);

It uses a technique from this answer to extract the epoch from the JSON date.
