TimeLogicAdapter: Unexpected return of confidence value 1

Issue: Unexpected return of confidence value 1

My understanding: When creating a TimeLogicAdapter with no additional parameters, the default positive and negative lists are applied. When hitting the positive list, confidence level is expeted to be set to 1, when hitting the negative list, level will be 0.

From the 4 examples below, the TimeLogicAdapter two times incorrectly indicates confidence level 1.

Question 1: 'What is 4 + 9?' TimeLogicAdapter returns 1.

Question 2: 'What time is it?' TimeLogicAdapter returns 1.

Question 3: 'What is AI?' TimeLogicAdapter returns 1.

Question 4: 'What is your favorite number?' TimeLogicAdapter returns 0.

While 2 and 4 the Adapter returns the correct confidence level, on question 1 and 3 returning 1 while not hitting the Adapter's default positive list, to me, seems to unexpected behaviour and in case of 3 leading to a incorrect answer. Also, I'm wondering why the Adapter returned 0 in question 4 while it returns 1 in question 3.

Did i miss something or is this unexpected and inconsistent behaviour?
