> STREAM, pseudo-clock, insert facts after advancing the clock to the timestamp in the event:
>     for( Job job: jobs.getJobs() ){      
>       Date jobTime = job.getTimestamp();
>       long newClock = jobTime.getTime();
>       if( newClock > oldClock ){
>         clock.advanceTime( newClock - oldClock, TimeUnit.MILLISECONDS );
>         oldClock = newClock;
>       }
>       System.out.println( "inserting " + job );
>       session.insert( job );
>       System.out.println( "advancing by 1ms" );
>       clock.advanceTime( 1, TimeUnit.MILLISECONDS );
>       oldClock++;
>       System.out.println( "fireAllRules" );
>       session.fireAllRules();
>     }
> A single rule:
> declare Job
>   @role( event )
>   @timestamp( timestamp )
>   @duration( duration )
> end
> Part of output:
> inserting Job: 6 at Wed Nov 03 01:40:00 CET 2010 - 1000
> advancing by 1ms
> clock: 1288744799999, ts of 1st: 1288742400000 - Average interval: 599 seconds
> clock: 1288744799999, ts of 1st: 1288743000000 - Average interval: 449 seconds
> fireAllRules
> inserting Job: 7 at Wed Nov 03 01:45:00 CET 2010 - 1000
> advancing by 1ms
> clock: 1288745099999, ts of 1st: 1288743000000 - Average interval: 524 seconds
> clock: 1288745099999, ts of 1st: 1288743600000 - Average interval: 374 seconds
> fireAllRules
> Rule firing is erratic. There is no apparent reason why this should fire twice after advancing the clock.
