Different age verification techniques offer different resolutions.

For example, if your watch has a second hand, you can count seconds. If someones watch only show minutes, the only minutes can be gauged- same for hours.

If you try to measure a duration that spans a century, but the reolution on your "watch" is a million years, then you will never resolve an event to less than a million years. Get it?
