You can just remove the last 4 characters, and use this timestamp in Date constructor:

new Date(+str.substr(0, str.length - 4))  

However, JS doesn't support "dd/mm/yyyy" format, and you will have to implement it yourself or use third-party libraries like Moment.js.

Here is the working demo:

Date.parsePubNub = function(str) {
    return new Date(+str.substr(0, str.length - 4));
};

Date.prototype.toDDMMYYYY = function()
{
  return ("0" + this.getDate()).slice(-2) + "/" + ("0" + (this.getMonth() + 1)).slice(-2) + "/" + this.getFullYear();
};

var str = "14512768065185892";
document.body.innerText = Date.parsePubNub(str).toDDMMYYYY();
