My (current!) colleague Joanna Wiebe has put together a lot of great thoughts on time, how we perceive it, and how we communicate it with websites (in particular.)

Writer and teacher Alice Bailey said, “…time is the sequence of events and of states of consciousness as registered by the physical brain. Where no physical brain exists, what humanity understands by time is nonexistent.” In other words, if a tree falls in the forest and there is no observation of its descent, it fell in no time.
