What do you think about time?

I believe that there are several "types" of time, including relative time, apparent time, and absolute time.

Absolute time is an ideal scale of time. It is useful because it simplifies calculations dealing with the laws of mechanics. Now don't misunderstand me -- absolute time is real. It's just not necessarily the time that we perceive.
