Come to think of it, I experienced a kind of time distortion today during a class. The clock in the back of the classroom said 9:00 (the time that our class starts). However, I didn't know the battery in it was dead and apparently neither did our professor (he looked over at the clock near the end of class and was like "What?? It's still 9:00? that can't be right..."). Well, about 20 minutes into class, I looked at the clock and actually thought it was still the beginning of class. Well, about 20 minutes later, I looked at it again and the time was still the same. I then knew that the clock must be dead. However, it made the class seem a lot shorter today which I was really happy about.
