javascript is not updating the timer after a while – Blancer.com Tutorials and projects

i tested a simple timer code for showing timer in website. The timer working fine when i am on the page. But when i go the another page or site, after a while when i come back to the timer page i see that timer did not worked correctly in the interval.
Suppose i leave the page for 5 minutes. So when I will come back, I should see 00:05:00. But it is displaying 00:01:00 (around).
But if i dont leave the page it is working fine.
What is the solution?

<body>
    <h1 id="time"></h1>
    <script>
        timerElement = document.getElementById("time");
        let seconds = 0, minutes = 0, hours = 0;
        timerInterval = setInterval(function () {
            seconds++;

            if (seconds === 60) {
                seconds = 0;
                minutes++;

                if (minutes === 60) {
                    minutes = 0;
                    hours++;
                }
            }

            const formattedTime = `${String(hours).padStart(2, "0")}:${String(minutes).padStart(2, "0")}:${String(seconds).padStart(2, "0")}`;
            timerElement.textContent = formattedTime;
        }, 1000);
    </script>
</body>

</html>

Even I deployed this on github page. But result is same.
