"::ctime" has not been declared (SFML + C++11 in Code::Blocks)

[iQChange]

I started a project and I'll use SFML and threads. When using sf::Thread, everything is fine. When I tried to add C++11 (I didn't even change the code!), <ctime> shows all stuff inside namespace std (in the file) is not declared. What's happening? How can I fix it?

Ok, so I understand why it's happening. SFML/System/Time.hpp is messing up. What should I do?

No, it's wrong. Just ctime messing up. :|
