I am interested in analysing transaction latency in Ethereum (time it takes from creating the transaction until it has been added to a block). I have been looking at Web3 (link https://web3js.readthedocs.io/en/v1.5.2/), and i can only find the time when the transactions is added to a block (block timestamp), but not when it was created by its submitter.
My question is there any clue to find the actual creation time for ethereum transactions, so that i can estimate the transaction latency?
