How to fix the error on localstorage in angular

How to fix the issue? cause I'm trying to console the elapsed and remaining when I try to reload and it will continue the time. but I'm getting an error which is the :

Argument of type 'number' is not assignable to parameter of type 'string'.

The right-hand side of an arithmetic operation must be of type 'any', 'number', 'bigint' or an enum type.

An argument for 'value' was not provided.

Here's the full code:

LIST = [{
    "id": "1lqgDs6cZdWBL",
    "timeUpdated": "2020-04-22 12:51:23",
    "status": "CLOSED"
}, {
    "id": "C2Zl9JWfZHSJ",
    "timeUpdated": "2020-04-22 12:51:07",
    "status": "CLOSED"
}, {
    "id": "BHbiVcCaQa2d",
    "timeUpdated": "2020-04-15 14:53:12",
    "status": "CLOSED"
}];


ngOnInit() {
  this.initializeAlertTimer();
}
initializeAlertTimer(data?: any, duration?: any) {
const DURATION = duration < 0 ? 1000 : duration;
    localStorage.setItem('DURATION', DURATION);
        localStorage.setItem('start', Date.now());
    
        const elapsed = Date.now() - localStorage.getItem('start');
        const remaining =  localStorage.setItem('DURATION')
    
  setTimeout(() => {
  }, DURATION)


}

addData() {
  const data = {
     "id": "qHFw59mujN9X",
     "timeCreated": "2020-03-06 12:21:06",
     "status": "NEW",
   }
   this.initializeAlertTimer(data, 20000);
}

also what I'm trying to do here is when opening the application it will list all the data LIST from the console once even it will change a page or reload the page it shouldn't repeat and when clicking on the addData() it will add the new data then by initializeAlertTime() it will display the newest data.

You can only store strings in localstorage. Try this:

localStorage.setItem('start',JSON.stringify(Date.now()));

And then:

  const elapsed = Date.now() - JSON.parse(localStorage.getItem('start'));

Try this -

const elapsed = Date.now() - (+localStorage.getItem('start'));
