You can look it up.
Frozen means solid not absolute zero. Solids still have atomic vibration motions.
Absolute zero is defined as when atomic motion stops. It doesn't mean that sub atomic motion stops. It doesnt mean that time stops. As long as there is motion or change of any kind, even at a sub atomic scale, there is time.
Certain particles are thought to have no sub atomic motion. That means there is no change of any kind in them, and are therfore thought to experience no time. However certain experiments with those particles show they do change.
