how do you feel about the STL project?

We already can, but to an infinitesimal extent.
Whenever you move you experience time dilation, though of a tiny amount.
As I recall, the Apollo 12 astronauts came back a couple of seconds 'younger' than people on Earth, because they were moving at great speeds.
We cannot do the below, where the effect becomes noticeable, but we can do things that are similar but to a vastly smaller degree, which will have an effect [though of a tiny magnitude].
If you make a cylinder of Neutronium [or something similarly dense] with a diameter similar to the Sun, and set it spinning so the surface is moving at near light speed, and then go in your spacecraft in an orbit that just grazes the surface, you will go forward or backward in time, depending on whether you are going with or against the spin of the cylinder [I may have those interchanged].
This is called frame dragging. It is predicted by the equations of relativity. This is real honest [though way out] physics.
Google 'closed time like curves" for more information.

You can't manipulate something that does not exist. Man created time in order to be able to calculate the speed and distance of motion. Think about it.

Given the extream amount of energy reqired to manipulate time, no.

we would need to reach a very high speed first

No. too short

I think we already do!
