Unreliable datetimes is just part of AT and something you need to deal with. The moment you start ingesting the firehose you'll see plenty of backdated or forward dated traffic. If you build feeds you need to be careful when using posted timestamps to sort feeds because of backdating and because there's no real centralized way to verify your timestamps. For my feeds I just reject posts that are beyond a certain delta from now and sort my feed by ingestion time rather than post time. There's probably some sort of blockchain-based time-attestation like [1] that could help but this is beyond the scope of AT and something that probably needs a lot more thought before a serious proposal comes forth.
