Template:Wallet date explainer

The date is not strictly required, but it makes the recovery process drastically quicker. Without a date, bitcoinj (the library Bisq uses to interact with the Bitcoin network) will resort to traversing the entire Bitcoin blockchain from 2013 (sometime around block 260,000) in order to rebuild your wallet state, and it will take a very long time. Specifying the date your wallet was created cuts recovery time significantly by telling bitcoinj where to start traversing the blockchain.
