> Introduce new StatisticsClock interface. An instance will be created during
> Cache creation. The method isEnabled() will be configured by
> system.getConfig().getEnableTimeStatistics() and getTime() will return
> System.nanoTime() if enabled or zero if disabled. This instance will be
> passed around and injected as a dependency via the constructor of each class
> that uses it.
