I used the API of Ethereum to download some transactions info. The timestamp is included, however I found the timestamp not mean the transaction time but the block which this transaction is located founded time. I visited https://etherscan.io for this transaction info. The same is true, the page shows me the time of the block which this transaction is located founded time. How can I get the transaction time rather not block founded time?
All transaction in a specific block were executed at the same time.
blockTime. I hope this makes sense.
On Ethereum, the all transactions in a block are processed at the same time and given the same timestamp. This is the same as the timestamp of the block that it is included.
In order to get the timestamp of a specific transaction, simply look up the timestamp of the block that that transaction is included in.
I think what he meant is if there is a difference between the
transaction creation time and
transaction execution time or equivalently as you two put in your answers,
block creation time. I did not find any information on if transaction creation time is logged. It's supposed to be a functionality of wallets, yet, they may not do the logging.
