Equating knowledge with true belief--think about the difference between someone who believes it is 3:12 when it is actually 3:15, and someone who justifiably believes it is 3:15 when it actually 3:15. According to what you are saying they can both *know* what time it is. Do you see how odd it is to think they can both know the correct time when only one of them is actually right?

They can't both know the time. Only one time is the correct time so only one person can know the time. Look at the requirements again for justified true belief.
