Examples of Chrono

Chrono is a simple chronometer @author www.b23prodtm.info
umontreal.iro.lecuyer.util.Chrono
The {@link Chrono} class extends the {@link umontreal.iro.lecuyer.util.AbstractChrono AbstractChrono} class and computes the CPU time for the current thread only. This is the simplest way to use chronos. Classes AbstractChrono, {@link umontreal.iro.lecuyer.util.SystemTimeChrono SystemTimeChrono}, {@link umontreal.iro.lecuyer.util.GlobalCPUTimeChrono GlobalCPUTimeChrono} and {@link umontreal.iro.lecuyer.util.ThreadCPUTimeChrono ThreadCPUTimeChrono} provide different chronos implementations. See these classes to learn more about SSJ chronos, if problems appear with class Chrono.
