Based on Ben's answer, I created the following util. You can tweak the sampling duration, however I use it just like this for token refreshing:

const absoluteSetInterval = (handler, timeout) => {
  let baseTime = Date.now();
  const callHandler = () => {
    if (Date.now() - baseTime > timeout) {
      baseTime = Date.now();
      handler();
    }
  };
  return window.setInterval(callHandler, 1000);
};

const absoluteClearInterval = (handle) => window.clearInterval(handle);
