      var datetime = new Date();     datetime.setTime(time);     var year = datetime.getFullYear();     var month = datetime.getMonth() + 1 < 10 ? "0" + (datetime.getMonth() + 1) : datetime.getMonth() + 1;     var date = datetime.getDate() < 10 ? "0" + datetime.getDate() : datetime.getDate();     var hour = datetime.getHours()< 10 ? "0" + datetime.getHours() : datetime.getHours();     var minute = datetime.getMinutes()< 10 ? "0" + datetime.getMinutes() : datetime.getMinutes();     var second = datetime.getSeconds()< 10 ? "0" + datetime.getSeconds() : datetime.getSeconds();     return year + "-" + month + "-" + date+" "+hour+":"+minute+":"+second; };
