Class TimeServices

java.lang.Object
  org.LatencyUtils.TimeServices

public class TimeServices
extends Object

Provide an API for time-related service, such as getting the current time and waiting for a given period of time. By default, these services are provided by actual time services in the JDK (i.e. System.nanoTime(), System.currentTimeMillis(), Thread.sleep(), and java.util.concurrent.locks.LockSupport.parkNanos()). However, if the property LatencyUtils.useActualTime is set to "false", TimeServers will only move the notion of time in response to calls to the #setCurrentTime() method.
