Javascript localStorage example with timestamp

script.md

I would suggest to store timestamp in the object you store in the localStorage

var object = {value: "value", timestamp: new Date().getTime()}
localStorage.setItem("key", JSON.stringify(object));

You can parse the object, get the timestamp and compare with the current Date, and if necessary, update the value of the object.

var object = JSON.parse(localStorage.getItem("key")),
  dateString = object.timestamp,
  now = new Date().getTime().toString();

compareTime(dateString, now); //to implement
