Kip Thorne has postulated such a machine, but no one has built one for reasons that will be obvious.
First of all, you need a flat region of space. Space is flat when there is no mass to distort it, so you are going to have to be far away from any stars.
Second, you need a hollow tube built of the matter that makes up neutron stars.
Third, you need something really heavy, such as a small asteroid, to which one end of the hollow tube will be gravitationally attracted.
Now, tether your asteroid to a really fast ship capable of going some real percentage of the speed of light, say .4c. Start traveling in a circle, dragging the asteroid behind you. The one end of the neutron tube will follow you.
Because an object in motion experiences a Lorenz contraction in time, the time at the end that is following you will travel slower than the other end. Eventually the two ends will have a noticeable time difference, with the stable end being farther in the future than the end that has been moving. Let's say that you arrange it so that the moving end is now one hour in the past than the stationary end.
Now drag the moving end so that it is near the end that was stationary.
If you now take your ship (release the asteroid--you're done with it) and enter the stationary end at 2:00, you will shortly emerge from the end that moved at 1:00. You could then transit back to the stationary end, go through again, and be another hour earlier.
One limitation to this is that it is impossible to travel back in time before the existence of the tunnel.

Reading the last answer makes me think that the hollow tube could be our solar system were the sun is the heavy object and earth is the traveling starship or in a broader view our galaxy is the hollow tube or maybe this universe is the hollow tube. Problem is that we have not understood yet how to manipulate it.

yes its called a telescope, In observing soles-tier objects in our Galaxy the more powerful the telescope the further back in time you can look, Right now we are seeing things that happend billions of years ago and just arriving here as there were at that time. So the further you can see, the more recent the information obtained.

theoretically, yea, but it would require an object or a radiation or such to travel faster then the speed of light, which hasnt been found yet..so, no, no one made a time machine ..yet..

No, we do not yet possess the technology for time travel. Perhaps within 500 years we will....if we are still here.

Who told you about my time machine?!?! It's not really a time machine. They're lying!

If some one is going to, don't you think they would have come back to our time already?

no but we have invented molecular teleportation,which is one step away from molecular time travel!
