[rules-users] scheduled starting of a ruleflow-group / drools fusion docs

Hi, 2 questions: 1. I want to start a ruleflow-group for e.g. only once a day? I am not interested in the pattern matches during the complete day, just interested in the result of the single computation. My ruleflow-group is ordered using a salience, the final/last rule should be processed once a day, repeating at the next day, and so on... I found the example like this StockTick( symbol == "RHAT" ) over window:time( 60 ) (...that happened in the last 60 clock ticks...) What is declared as "clock ticks"? 2. I guess that drools fusion can solve my problem, is some more detailed doc available at this moment? (more than the ´pure´ headlines containing doc I found everywhere?) Thanks for advice, including just giving keywords! Thorsten
