Exactly. Also, you need to make sure you "tell the engine" everytime your Time object change, as well as ensure that fireAllRules will be called at the exact time: 22:00, because if it is called 1 minute later or before, the constraint will evaluate to false.

Claudio, this would probably work if you fire the rules every hour or
every minute or every time your Time object changes. Just having the rules
sitting in your rulebase doesn't mean they get executed.
