How do i set a time for someone to be on a scene?

What is the c# code for someone to be on a scene for 10 seconds then go to the next scene. What would i attach the code to. The Main camera?

MainCamera is fine, any GObj in the scene will do.
There are many examples of ‘how do I run a timer’ in UA

Here’s one

startTimer
whenceTimerDone
Application.loadlevel(next)
