Manya,
please do not open two threads for almost the same question!
1.end_timestamp must be > start_timestamp this is the condition.
1.start_timestamp can not be =< Current Date this is the condition.
First, I think, "can not be <=" is the same as "must be >".
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):
SomeClass(startTimestamp < endTimestamp, startTimestamp > $currentTimestamp)
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.
If you have your solution without DSL it should not be difficult to cast and
abstract this into a DSL.

I must say, I don't know how to write the rule even without DSL... ;o)
Not with this information.
For me it looks like a kind of meta-information about the facts, but if not,
think, if "can not be updated" is a kind of property, which can be expressed
as constraints on some facts and their fields.
