Hybrid Logical Clocks
neat substitute for physical-time clocks in synchronization and ordering in a distributed system, based on Lamport's Logical Clocks and Google's TrueTime.

'HLC captures the causality relationship like LC, and enables easy identification of consistent snapshots in distributed systems. Dually, HLC can be used in lieu of PT clocks since it maintains its logical clock to be always close to the PT clock.'
