> When using a custom @timestamp together with PSEUDO clock, all events are accumulated rather than just those within the window:time period.  I have tried using long (millisecond) and java.util.Date without success.
> ==================================
> declare SimpleObject 
> 	@role(event)
> 	@timestamp(customTime)
> 	@expires(10m)
> end;
> rule "honour custom timestamp"
> when
> 	$avgVal : Number (longValue > 0) from accumulate ( SimpleObject($valueLng : valueLong ) over window:time (10s) from entry-point "SimpleEP", average ( $valueLng ) )
> then
> 	System.out.println("avg: " + $avgVal);
> end
> ---------------------------------------
> import java.util.Date;
> public class SimpleObject {
> 	
> 	private long customTime;
> 	public long valueLong;
> 	
> 	public SimpleObject(Date customTime, long valueLong) {
> 		this.customTime = customTime.getTime();
> 		this.valueLong = valueLong;

> 	public long getCustomTime() {

> ==================================
> OUTPUT (INCORRECT - all values are included for each evalutation):
> avg: 100.0
> avg: 95.0
> avg: 90.0
> avg: 85.0
> avg: 80.0
> avg: 75.0
> Note that when commenting out the @timestamp tag the output changes to the following (correct) output:
> avg: 100.0
> avg: 95.0
> avg: 90.0
> avg: 85.0
> avg: 80.0
> avg: 75.0
> avg: 70.0
> avg: 65.0
> avg: 60.0
> avg: 55.0
> avg: 50.0
> Also note that when using the REALTIME clock with Thread.sleep the output is correct.
