When using the `rescanblockchain` wallet RPC command, it seems like sometimes (though not always, and I couldn't find a specific pattern for when this does and doesn't happen) the `time` field of all transactions found is being set to the time of the most recent transaction detected. Besides that field, all data (including block and blocktime) return correctly. What's more, even in a node with `txindex=1` this happens, despite that when calling the (non-wallet-specific) `getrawtransaction` command, it returns the correct time.

Here's an example of a testnet transaction where I experienced this behaviour, and the output of Core where the same `txid` has. 2 different `time`s - a correct one using `getrawtransaction` and an incorrect one using `gettransaction`:
