Consider the following KB:

rule "Dummy timer rule 1"
timer (cron: 0 0 0 * * ?)
when
	Integer()
then
	insert("Dummy timer rule 1");
	System.out.println("Dummy timer rule 1");
end

rule "Dummy timer rule 2"
timer (cron: 0 0 0 * * ?)
when
	Integer()
then
	insert("Dummy timer rule 2");
	System.out.println("Dummy timer rule 2");
end

Then consider the following steps:

    insert new Integer
    advance clock by +1 day

Expected result: 3 facts in the working memory, the original Integer, and two String.

Actual results: 2 facts in the working memory, the original Integer, and only 1 String, from the former of the two rules.
