`std::chrono::duration_cast` non-member function

Explicitly convert a std::chrono::duration object to a specific std::chrono::duration instantiation.

template <class ToDuration, class Rep, class Period>
constexpr ToDuration duration_cast(const duration<Rep, Period>& d);

Requirements:: ToDuration must be an instantiation of std::chrono::duration.
Returns:: The duration d converted to the duration type specified by ToDuration. This is done in such a way as to minimize any loss of precision resulting from conversions between different scales and representation types.
