Puzzle:

Alice, who is in an Atlantic seaboard state (one of the states of the USA, that is) is talking on the phone to Bob, who is in a Pacific seaboard state (again, one of the states of the USA). "What time is there?," Alice says. Bob gives the correct time where he is. "Funny, it's the same time here," says Alice. How is that possible?

Thanks to Warren Usui for the problem.
