A timestamp is a numerical value that represents the amount of time that has passed since the Unix epoch (1st Jan 1970) and you get the number of milliseconds since then with the Date.now() function in JavaScript.
So you might want to divide this by 1000 and round it to get the number of seconds which is more commonly used for timestamps.
Date.now(); // Milliseconds
Math.round(Date.now() / 1000); // Seconds
