Time-based Leases and Inverval Clocks (Spanner)

We now revisit the notion of physical clocks, breaking down the latest advancements made within the last years in the field of distributed, geo-replicated data systems.  We then examine two time-driven abstraction variants that have resulted into significant speedups in cloud computing: time-based leases and interval clocks and discuss motives, solutions, and implications.
