KSP how can I revoke the time ?

[berkekrkn]

I've launched a my rokcet and built an orbit. But I can't revert to veichle assembly. So is it possible to revoke the time 1 or 2 days ago maybe ?

The only time you can "revert to launch" or "revert to vehicle assembly" is if you have been continuously flying the same rocket since it was launched without interruption.  "Interruption" includes switching to another ship, going back to KSC, or loading a saved game.

So the short answer is "no, you can't."

That said:  The game does allow you to save and load games.  F5 will quicksave (instant one-key save), and holding F9 will load the quicksave.  Alt-F5 lets you save to a named file, so you can have as many named saves as you want; Alt-F9 will load a named save.

So in general, if you want the ability to "go back in time", you need to get in the habit of saving.  For example, if you had saved 2 days ago, you could easily do what you want (go back in time) just by loading the save that you made.  But since you haven't done that, you can't.

Revert only works if you never take your focus away from the ship.  If you ever change to another ship or go back to KSC, or if you load a quicksave or quit the game and restart it later, you can no longer revert.

It is thus possible to do a complete interplanetary mission and land back at Kerbin, then hit revert instead of recover, PROVIDED you never took your eyes off the ship.  OTOH, if you get the ship to orbit then leave it there to do something else in the game or quit the game, then you can't revert anymore.

Only if you made some named saves or quicksaves (F5, Alt-F5). If you did, you can go back to one of those by hitting F9 (quickload) or Alt-F9 (pick any save in the list).

One tip: do an Alt-F5 first, just in case whatever other save you load turns out to be worse. At least you can then return to the current one.
