there is nothing like real and un real in this universe.... everything in this universe is relative... so there is nothing like real time..time as u would know is dependent on space.. so different areas have different clocks...for example let's say a fly lives for 1 day then it experiences time as same way as we would if we lived for 70 years... so 1 sec of our life ,for a fly is more than 1 sec in it's life...as the metabolic activities of a fly are on a different time scale than ours.... hope ,u'll understant wat i mean... think about it to understand better...!

The clocks that run the fastest are those that are far from any source of gravitation. One might therefore say that a clock in intergalactic space, at rest with respect to the cosmic microwave background, was the "true" time of the Universe. Such a clock would tick faster than any other clock in the Universe, and all other clocks would be slower because of relativistic effects.

In special relativity, there is no 'real time'. Time is always relative to the observer. However, in general relativity, there are preferred observers: those that are at rest relative to local matter. Galaxies are usually very close to being such preferred observers. It is these observers that are used when talking about the age of the universe, for example.

A good way to find a preferred observer is to look at the background radiation. For a preferred observer, the background radiation has not diploe moment. The earth is moving about 300 km/sec with respect to this background radiation.

Every clock represents 'real' time RELATIVE to the clock's point of view.

There is no absolute time, mass or length - only an absolute measurement of the speed of light. Time, mass and length are dependent on the observer's frame of reference but the speed of light looks the same to everyone regardless of the frame of reference.

All frames of reference are equally valid regardless if they agree or disagree. That's Relativity for you.

All time is relative in relativity. The only "real" thing is the speed of light. The speed of light is the only thing that always appears to same to everyone. In everyday experience time and space never change and speed changes, so it is hard to accept that speed, or at least the speed of light, is the thing that never changes and both time and space are the variable things that change all the time, but that is exactly what relativity says.

Nope. It runs differently in many different parts of space, there is no "one true time". Just an average.
