Let's add the new checks inside this method so that this method can also handle fallback.

I intentionally kept that super simple.
It just takes in timestamps while this function handles all the complex logic.
The caller can choose to keep things simple using the other function or use this function if a logical interpretation of the ZK metadata is needed.

I dont think that a good idea to leave to caller to understand the difference. Caller can call any method and both method should be consistent.
Passing invalid timestamp in second method behaves differently than the other method.
