org.quartz.simpl
Class SimpleTimeBroker

java.lang.Object
  org.quartz.simpl.SimpleTimeBroker

All Implemented Interfaces:: org.quartz.spi.TimeBroker

public class SimpleTimeBroker
extends java.lang.Object
implements org.quartz.spi.TimeBroker

The interface to be implemented by classes that want to provide a mechanism by which the org.quartz.core.QuartzScheduler can reliably determine the current time.

In general, the default implementation of this interface (SimpleTimeBroker- which simply uses System.getCurrentTimeMillis() )is sufficient. However situations may exist where this default scheme is lacking in its robustsness - especially when Quartz is used in a clustered configuration. For example, if one or more of the machines in the cluster has a system time that varies by more than a few seconds from the clocks on the other systems in the cluster, scheduling confusion will result.

void shutdown()
           Called by the QuartzScheduler to inform the TimeBroker that it should free up all of it's resources because the scheduler is shutting down.
