[rules-users] Time Units Support - execution and repeating period

[Trägenap]

Hi,

I want to realize a rulebased condition-monitoring. Rules should fire 
only once a week, if a condition still is true. But they should 
processed once per hour. So, first I have to realize a exceution period 
(e.g. once per week) and a test/repeating period to check new conditions.

I just read something about time units support and timer nodes, but do 
not find more detailled manuals.

Are addtional features in drools available, to support this requirement?
Where I can find more information, examples about time unit support?

Thanks a lot.
