Transaction dates in Bitcoin-Qt

[warut]

My previous wallet was so old that the 100 pre-generated addresses were all created with uncompressed public keys. But I wanted any new addresses of mine to be made from compressed public keys to reduce transaction sizes, so I created a new wallet in Qt 0.8.5 and then imported private keys of old addresses to it.

Now I notice that the dates shown on the transaction list of Qt are the dates that I imported the private keys, not the actual transaction dates, except for the 3 most recent transactions which are also shown on the Qt overview. Is this a bug? How can I make it show the actual tx dates instead?

Well, bitcoin transactions aren't timestamped. That time is simply an indicator of when your wallet learned of the transaction. If you import a private key, then the wallet learns about the transaction at that point. If you wanted to change those dates, you would need to edit the wallet database. However, if all you want to do is flush the keypool, you can do so by encrypting your wallet, which gets rid of all keypool addresses to ensure that any address you generate has never had its privkey touch your disk unencrypted. If it's already encrypted, I suspect changing the passphrase will cause a similar keypool dump, but I'm not sure about that.

But if bitcoin transactions aren't timestamped, how can Qt correctly show my last 3 tx dates?

Silly question, did you make the 3 most recent transactions since you have updated to 0.8.5?

OK, I get it now.

Any timestamps that a transaction has will either be "when did I first see this transaction", or "when did this transaction get confirmed".

the blocks that the transactions are in are timestamped
