First, I think, "can not be <=" is the same as "must be >".<br>
<br>
Drools is able to compare timestamps as primitive number types or as java.util.Date's. So without DSL you can directly (no matter, what type the timestamps are):<br>
SomeClass(startTimestamp < endTimestamp, startTimestamp > $currentTimestamp)<br>
where $currentTimestamp is a variable binding done earlier in the rule. Since clock support is introduced not until Drools 5, you have to insert a virtual clock object in the working memory, which you have to update with certain mechanism to the current system time.<br>
<br>
If you have your solution without DSL it should not be difficult to cast and abstract this into a DSL.<br><font color="#888888">
