Json DateTime Parsing In Android

Question

My API Gives This Result:

{
    "Posts": [{
        "UseName": "Robert Ray",
        "DateTime": "\/Date(1376841597000)\/",
        "PostText": "Welcome!!\u003cbr\u003eThis Is my Text"
    }]
}

I Parse My JSON Like This

try {
    Posts = json.getJSONArray(TAG_POSTS);

    for(int i = 0; i < Posts.length(); i++){
        JSONObject c = Posts.getJSONObject(i);
        String post_text = c.getString("PostText"); 

        String strDate = "2013-05-15T10:00:00-0700";
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm");
        Date date = (Date) dateFormat.parse(c.getString("DateTime"));
    }
} catch (JSONException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
} catch (ParseException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
} 

But Its Not Working, what I want is It should calculate the time elapsed since the User posted the Post,
i.e we have to subtract the current data with the date in JSON, and then convert that in Minutes / Hours

Well I hope that you find this usefull:

String ackwardDate = "/Date(1376841597000)/";
//Dirty convertion
Calendar calendar = Calendar.getInstance();
String ackwardRipOff = ackwardDate.replace("/Date(", "").replace(")/", "");
Long timeInMillis = Long.valueOf(ackwardRipOff);
calendar.setTimeInMillis(timeInMillis);
System.out.println(calendar.getTime().toGMTString()); //Prints 18 Aug 2013 15:59:57 GMT

But I'm saying, that date format in your JSON It's really ackwards, take the example of google, for a correct, standar, parsed JSON.
