If you check the very last lines of the raw transaction, you can find the 'time' field with the value of 2953429233. And the 'lock_time' is set to 0. Here is another transaction like the one from my original post: https://blockchain.info/rawtx/da71fda48795fbdf05ca522ceaa7ac34bef68ca6973f33ff5ec764bdfcff045c And again, "lock_time": 0, "time": 1574921809

@GSazheniuk yes, but then"time" field is something blockchain.info has made, it is not part of the raw transaction, that's what I said in my answer

Blockchain.info is a private website, it's not the block chain, most of the information they show is fairly nonsensical. They've a history of displaying misleading, incorrect, or just plain ridiculous things about transactions.

@MeshCollider Just our of curiosity - did you check raw transaction in any other source(s) when you said that 'there is no "time" encoded in a bitcoin transaction itself '?

@GSazheniuk I'm very familiar with the raw transaction format :) you can see the two transaction serialisation formats here: https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#transaction-id

That looks like a glitch with blockchain.info, there is no "time" encoded in a bitcoin transaction itself so that number is likely just when blockchain.info received the transaction.

In general though, it is possible to create a transaction which is only valid after a certain point in time or a certain block height in the blockchain, by using the "locktime" component of a transaction. If a locktime on the transaction is set, the transaction can only be included in a block after that point, not before, which may be of interest to you.
