You can simply do this with getTime() which returns the number of milliseconds.

var ds = "2014-03-26 10:52:00"; 
var newDate = new Date(ds).getTime(); //convert string date to Date object
var currentDate = new Date().getTime();
var diff = currentDate-newDate;
console.log(diff);

Sometimes there are chance for cross browser patibility in parsing the date string so it is better to parse it like

var ds = "2014-03-26 10:52:00";
var dateArray = ds.split(" ");  // split the date and time 
var ds1 = dateArray[0].split("-"); // split each parts in date
var ds2 = dateArray[1].split(":"); // split each parts in time
var newDate = new Date(ds1[0], (+ds1[1] - 1), ds1[2], ds2[0], ds2[1], ds2[2]).getTime(); //parse it
var currentDate = new Date().getTime();
var diff = currentDate - newDate;
console.log(diff); //timestamp difference

You can use MomentJS library

 var user_submited_time = moment('2014-03-26 10:52:00');
 var now = moment();
 var value = user_submited_time - now;
