Bitcoin-Qt listing all Transactions as occurring at same date and time Any ideas about this one? I've imported addresses into my wallet and on rescan, all transactions come up as same date and time?
I've also had the same issue whereby importing a private key using RPC Console importprivkey will rescan and tag it with the time which the rescan takes place in btc-qt. 

Even Multibit which uses the following format for private key (*.key) files is only dated such that the date corresponds to what is assumed to be the key's creation date:

As mentioned, the Blockchain is not being consulted for transaction history - a major flaw IMO.
