[rules-users] Unpredicatable output with Temporal rule

[PriyaKathan]

Here is the Code Snippet:

            currentTimeStamp = getCurrentTimeStamp(tuple, schArray);// the
method will the timestamp of the tuple

            this.clock.advanceTime(currentTimeStamp -
clock.getCurrentTime(), TimeUnit.MILLISECONDS);
            this.ruleSession.fireAllRules();

I use Pseudoclock. The events are fed into the engine as stream of data.
