People sign the events themselves, surely they can verify the timestamp. Relays can reject stale or future timestamps at publish.
The issuance doesn't have to be TEE, it can also be smart contracts....

Yeah, that's what they normally do. Anyway, that requires that we trust these relays to some degree, that they don't leak the data (if it's not encrypted), and that they verify the timestamps and check that the deadline hasn't happened yet. And they possibly need to survive DDoSing. Something blockchain-based could make it unnecessary to trust the relays.
