Timestamp	RaftKVTransaction.getLastStateChangeTime()	Get the Timestamp of the most recent state change.
Timestamp	Follower.getLeaderTimestamp()	Get the most recent (leader's) request timestamp returned by this follower in a response, if any.

Methods in io.permazen.kv.raft with parameters of type Timestamp

Modifier and Type	Method	Description
int	Timestamp.compareTo(Timestamp that)	Compare two instances, where "smaller" means earlier in time.
protected boolean	Role.isLeaderLeaseActiveAt(Timestamp time)	Determine whether the leader's lease timeout extends past the given time, that is, it is known that if the current leader is deposed by a new leader, then that deposition must occur after the given time.
int	Timestamp.offsetFrom(Timestamp base)	Get the number of milliseconds this instance is offset from the given instance.
