'timeScale' is not a member of 'Time'

I want to use Time.timeScale in my project, but everytime i do so Unity gives me the following error message: ‘timeScale’ is not a member of ‘Time’. I’ve copied and pasted the code stated in the Documentation into my project, but still received the same error message. Then I kindly asked Google for help, but it seems that noone has a similar problem.

Thanks in advance for every answer you can provide me.

Regards

Make sure you don’t have another class / component named time?

If you do, you can still access it by doing UnityEngine.Time.timeScale
