Unfakeable, true timestamp

[ghost]

In a future of more NFT use, proof of originality would be important in terms of establishing genuine ownership: just reference the first minting. There are currently methods to get a "timestamp" eg ( https://ethereum.stackexchange.com/questions/9858/solidity-is-there-a-way-to-get-the-timestamp-of-a-transaction-that-executed ) but they are indirect and complicated.

IOTA would stand out if it were technically feasible to embed a true timestamp in such a way that it cannot be modified, and cannot be arbitrarily chosen upon creation. The question is open as to where the best place would be for the feature- on the ledger, or in the smart contract.

There are a range of other useful applications of such a hypothetical feature besides the NFT proof of originality benefit.
