Interface Clock

All Known Implementing Classes:

Clock.Default

public interface Clock

Wrapper around time related functions that are either implemented by using the default JVM calls or by using a custom implementation for testing purposes. See Clock.Global.instance for how to use a custom implementation. Please note that Clock wasn't used, as it would not be possible to provide an implementation for nanoTime() with the exact same properties of System.nanoTime().
