Getting the timestamp of a transaction

[tqbl]

According to the docs, a TransactionResponse object has a timestamp property that is non-null if the block has been mined. For me, the timestamp is null even if the block has been mined. Here is some code where I'm using Infura as a provider:

const provider = new ethers.providers.InfuraProvider('mainnet', apiKey)
const txAddress = '0x5ec10915d5b3c44ae5d41f5d2b4b4864dbada014e9dc2254e5d44568b1039edf'
provider.getTransaction(txAddress).then(tx => {
  console.log(tx.timestamp)
})

Shouldn't tx.timestamp return the timestamp? Or am I missing something?

provider.getTransaction uses eth_getTransactionByHash under the hood. And from the specs, a standard ethereum node doesn't give you a timestamp. Here if you need the timestamp you have to do another query to fetch the block provider.getBlock(blockNumber) and get the timestamp from there.

But there can be some non-standard backends who do give timestamp, so in that case, it may helpful to include timestamp in TransactionResponse and we need to update the docs about this.

Got it. Thanks.
