public class ContinuousClock
extends AbstractClock
implements IContinuousClock

A continuous clock represents a real time clock that is based on the hardware clock. Can be made faster or slower and also has an adjustable start time.

                       long delta,
                       IThreadPool threadpool)

Create a new clock.

Parameters:

name - The clock name.

starttime - The start time.

dilation - The dilation.

delta - The tick size (in millis).
