        "total_results": 500,
        "results_remaining": 490,

                "start_time": 1392156202,

When receiving JSON data from the server through an XHR request, it is necessary to first parse it and convert it into a JavaScript object

var data = JSON.parse(json);

After parsing, you can access specific properties such as start_time as you would access any other property of a JavaScript object

data.result.matches[0]['start_time']
