"No time to look back" David Byrne said that. It's always now, it's always here. Time is in my head; kept by my biological entity, my body. Is it an alarm clock set to signal the next world? The time is what my trusty Timex wrist watch says it is. I am the Professor and the time in my class is exactly what I say it is according to me. The band "Chicago" sang a famous song: "Does Anybody Really Know What Time It Is?" They also sang "Twenty-five or Six to Four". Good Q!
