org.quartz.simpl
Class SimpleTimeBroker

java.lang.Object
  extended by org.quartz.simpl.SimpleTimeBroker
All Implemented Interfaces:
org.quartz.spi.TimeBroker

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

The interface to be implemented by classes that want to provide a mechanism by which the 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.
