This is exact same query you have started in your original post.

I have responded to that that I can add time.h and math.h without any issue and use their functions. 

I have explained all steps in detail that how I did that starting from the name of the project and noting smaller changes like the project configs etc.

1) Can you replicate the steps which I have mentioned and see the output?

2) Kindly let let me know all the steps in detail to replicate the problem you are having
