Hi @Capyhw,

I had to translate your message with Google Translate. Just for reference, this is what I got back:

For iOS versions below 15, I started a setInterval of 1000ms, logged in the callback, and found that it was logged many times within 1 second.

I created a little demo which aims to reproduce the error. It logs the elapsed time in milliseconds between the calls to the callback. It should only log numbers of 1000 or higher.

Could you please check what it logs on your device?

Hi @Capyhw,

thanks for providing further feedback. Can you please check if performance.timeOrigin is available on the device. MDN says it became available in Safari v15. I suspect that if it's not available, everything falls apart.
