var now = new Date();

var year = now.getFullYear();
var month = now.getMonth() + 1;
var day = now.getDate();

var hh = now.getHours();
var mm = now.getMinutes();

var clock = year + "-";

if(month < 10)
clock += "0";

clock += month + "-";

if(day < 10)
clock += "0";

clock += day + " ";

if(hh < 10)
