Define MonotonicClock interface for advanced timestamps
MonotonicClock can be implemented to provide more certainity about time than the standard System.currentTimeMillis() can provide. This can be used by classes such as PersonIdent and Ketch to rely on more certainity about time moving in a strictly ascending order. Gerrit Code Review can also leverage this interface through its embedding of JGit and use MonotonicClock and ProposedTimestamp to provide stronger assurance that NoteDb time is moving forward.

Ketch: Basic replication system
Git Ketch is a multi-master Git repository management system. Writes are successful only if a majority of participant servers agree. Acked writes are durable against server failures as a majority of the participants store all required objects. Git Ketch is modeled on the Raft Consensus Algorithm[1]. A ketch sailing vessel is faster and more nimble than a raft. It can also carry more source codes. Git Ketch front-loads replication costs, which vaguely resembles a ketch sailing vessel's distinguishing feature of the main mast on the front of the ship.
