What does best block time mean in wallet.dat I have a wallet.dat file that states:


Best block at time of backup was 42603 (0000000013136bd812212959a15ef0ea0f084ee2c64e2f7f0e127d198f67a37f),
mined on 2010-02-26T00:36:08Z


Does that mean that one of my address mined on that block?  Or is it just referenced with no correlation to my private keys with unspent coins?
Its the time the wallet was last synchronized to, it won't know about any transaction changes in or out past this time until it has been loaded again by a synchronized node. It has nothing to do with your transactions specifically.
