rosserial_windows help,compile error on windows

edit

I`m trying to use rosserial_windows . And I operate as the tutorial instructed . The difference is that I use visual studio 2010.

After Step 4--Add code to main for Hello World, I begin to build the code on visual studio 2010. And there are same errors with these two documents, duration.h , time.h :

error C3861: 'round': identifier not found

how can i solve this problem?

Is that because I didn`t use visual studio 2013 like the tutorial does??
