UNIX epoch time of the last block received from this peer that we had not yet seen (e.g. not already received from another peer), that passed preliminary validity checks and was saved to disk, even if we don't connect the block or it eventually fails to connect. Used as an inbound peer eviction criterion in CConnman::AttemptToEvictConnection.
