As said... Or written before:
Yes. It was done countless times. Even in antiquity. Even when we were created it was possible. But i do not think there was a need for that at that "time".
You see: Time as we "know" it (We do not know anything about it) is an illusion. Clocks are not even scientific measuring devices. They simply show you the current state of our sun. You could say it is an abstract sun measuring / positioning device. It is very flawed. We need to add leap years to make account for the unprecise "measuring" it does.
Anyway...
So, we do know that time is an illusion, so what?
Well, how about i say that "past", "present" and the "future" all happen at the same time?
Because of our many worlds, one is taking place in the past, the other, our current world for example is in the present and another one is playing in our distopian future.
What does that mean?
To get to the point:
If they all are seperate worlds, then one needs to tunnel through them to "travel" to time. You see i have added quotation marks on the word "travel".
Because what one really does when "time travelling" is moving from one place to another. Time does not change because it simply does not exist.
Different places with different settings exist on the other hand.
You are simply changing your current place. Or state. Or world...
I hope that was an somewhat comprehensible answer to your question.
