I just came across this Transaction: https://blockchain.info/tx/cf77c2b888916c0debfb801d3d129ba5b7f6445e0dd6db9238b313b51369024c
Received Time: 2063-08-04 05:00:33
Raw Transaction: https://blockchain.info/rawtx/cf77c2b888916c0debfb801d3d129ba5b7f6445e0dd6db9238b313b51369024c
Is it just one case, maybe some kind of bug, which has already been solved, or is this a normal behavior?
Is there any official information regarding this topic?

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.
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

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. – Anonymous – 2017-12-05T10:55:55.203
@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 – 2017-12-05T21:06:46.223

@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
