Timer Pause

I have made a GUI timer that counts how long you have been driving for on a game. My question is how do you save the time that the person got and then display it on the finish screen “Just a Camera looking at a grey cube with writing on it”.

Im not quite sure if this is what you are looking for but…

(this is also assuming the grey cube with writing on it is in a different scene.)

Maybe you could create an Empty GameObject and write a script that uses
DontDestroyOnLoad
while storing the time variable that the GUI Timer uses. Then after this u can access this variable for the use of displaying it.
