Are there different kinds of time in the universe?
We hear about the arrow of time which always 'points' in the same direction, but "where" is it pointing? And that entropy always increases--there is more room being created for events to occur, so more events occur and the universe contains more information "now" than it did "then".
Is time, locally speaking, something that always vanishes from any coordinate system? Does this imply that time is 'lost' because we can only determine periodic motion up to what we call precision, so we can only build (pairs of) clocks which will move periodically up to this precision, and which will then only be accurate (move at the same rate) to this degree?
Since we can't build 'exact' pairs of clocks and measure time 'precisely', then by definition, time, and timing, is something we have already lost--the precision/accuracy gap in measurement. Time vanishes as soon as you measure it. This lost information corresponds to gravitational intrinsic entropy, doesn't it?
