I am running a BTC core node and I would like to perform some experiments and analysis on Bitcoin transaction latency. However, I see that the method
getrwatransaction returns an object with:
"blocktime": xxx, (numeric) The block time expressed in UNIX epoch time
"time": n, (numeric) Same as "blocktime"
As I would like to get information on transaction latency, in a way that I can subtract the first appearance of such transaction in the mempool with the block creation epoch, those two parameters should not be the same, otherwise I only see it as a redundant and useless information.
Is there a way to get such piece of information? I see that mempool does not store (obviously) all the record of received transactions, so I was wondering whether such information is stored in the transaction itself, or if it is possible to get it somehow.
