Time is what a clock measures.
Imagine you have a best friend, living on a planet in the universe near one of the stars. You decided to talk on
http://bitcointalk.org by private message, at exactly 3pm.
Your friend, on the planet, is 94607304725808000 meters from earth.
He looks on his clock, it's 3 'clock.
You look on your clock, it's 3 'clock
Yet, he is not there
why is he late? how is this possible?
Say your internet speed is the speed of light: 299792458 metres per second. Remember the earth is 94607304725808000 meters from your friends planet, so it would take many seconds for a signal to go from the planet to you. (you can do the calculation if you wish). Thus, you get that the time, even for the most near stars or planets is not the same on both clocks.
In fact, this also happens on the smaller scale. Say the:
moon is at 356.400.000 meter from earth
lightspeed is at 299.792.458 meter / second. So your view of the moon, is little bit more than a second old.
Now imagine an nice lady 2 meters from you. But.. you do not see the lady, you see how the lady looked like
about 0.00000001 seconds ago.
0.00000001 seconds is not a big deal for us. Thus what a clock measures 'time' is connected with space.
This is a tiny tiny explanation of the theory of relativity by Albert Einstein. I tried to explain it as simple as possible.
