timestamping tx

[benjiqq]

how to determine timestamp of a tx in general? the block meta will arrive after the tx for commitment level processed? how to match the two for confirmed, finalized and processed

const req = {
slots: {},
accounts: {},
transactions: {},
transactionsStatus: {},
 blocks: {},
blocksMeta: { blockmetadata: {} },
entry: {},
accountsDataSlice: [],
};

when data arrives

const blockTime = data.blockMeta.blockTime.timestamp;
const slot = data.blockMeta.slot;
const currentTime = Date.now(); // Get the current local time in milliseconds
const timestamp = Math.floor(Date.now() / 1000);
const latency = timestamp - blockTime; // Calculate latency in seconds
