[TIMED] Time Dilation

In the theory of relativity, time dilation is an observed difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from gravitational masses. An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's own equally accurate clocks. This effect arises not from technical aspects of the clocks nor from the fact that signals need time to propagate, but from the nature of space-time itself.

Interesting Huh... ok well, anyway... :-)
