Why won't setInterval function properly with innerHTML?

Question

Why won't setInterval function properly with innerHTML?

I've been attempting to include a small feature on my website that displays the running seconds, but for some reason my JavaScript function isn't working. Strangely, it's not throwing any errors either. Here's the code I'm using:

function stoptime() {
    let count = 0;
    count = count + 1;
    stop = document.getElementById("time");
    stop.iinnerHTML = count.value;

setInterval(stopt ime, 1000);

I tried using this code with the document.write function, but instead of incrementing the count ++ value, it just displayed numerous single values of count. So I attempted to use innerHtml, but it still didn't work.

Could you please advise on what might be causing this issue and provide the correct code?

The variable count is always initialized within the same function scope, causing it to reset to 1 every time the function is called. To resolve this issue, consider moving the declaration of count outside the function.

Additionally, there is no need for count.value in this context.

let count = 0;
function stoptime() {
    count = count+1;
    stop = document.getElementById("time");
    stop.innerHTML = count;
}
setInterval(stoptime, 1000);

<div id="time"></div>
