Start, Stop and Reset a Timer with C# scripting [Unity 2018 Intermediate tutorial]

Hour does not work. After 60 minutes, Its continues, 61 - 62.
How do we do this, I will be glad if you tell. And how can we record it?
such as high score. The player tries to finish the game in a short time.

hey! what's the difference in the code if I want the timer to go backwards?
thanks for the tutorial :)

Okay, so is there a way to record it?

Reset button has a problem. Just say 00, doesn't work function as a reset. I want to know the solution
