+- This hybrid logical clock crate implements a hybrid logical clock (HLC) construct designed to combine physical and logical timestamps.
+- The clock can be used in distributed systems to efficiently order events while minimizing the reliance on synchronized physical clocks.
+- Each timestamp consists of a wall-clock time and a logical component, allowing for easy comparison and conflict resolution.
+- This crate is an implementation of the [Hybrid Logical Clock](http://www.cse.buffalo.edu/tech-reports/2014-04.pdf).
