Answer:
This statement is an example of An alibi
Step-by-step explanation:
What is an alibi in a court case?
An alibi is a proof that someone who has been accused or suspected of a particular crime gives as an evidence in court in order to prove that at the time in which the crime was committed the person was in another place away from where the crime was committed.
Timothy says he just knocked off from his shift around 10:00 PM and the crime was committed around 10:05 PM and if he says it takes 20 minutes from where he works to get to where the murder was committed that means he couldn't have made it to that point in just 5 minutes and that is Timothy's alibi which if the court needs to confirm can use cameras around the subway area or any clocking system that Timothy uses to check out at his work place .
