Bug 131607 – Changing system time when using SetInterval()

• Component: New Bugs
• Status: NEW

[Marek]

Using setInterval() or setTimeout() in Javascript code and changing system time backward for example 1 hour causes browser (newest Safari)/ or engine (older version of QT WebKit) to freeze.

Sample code:
HTML:
<p id="date"></p>

JS:
setInterval(SetTime, 1000);
function SetTime() {
document.getElementById('date').textContent=new Date();
}

OR:

(function loop() {
document.getElementById('date').textContent=new Date();
setTimeout(loop, 1000);
})();
