That's saying that the compiler can't find any constructor function matching your number and types of arguments, in your case two uint8_t values. C++ allows many constructor functions for a class as long as they are unique in the number and type of arguments. The compiler tries to match your code to the defined signatures* in the header file. You solve the problem by looking at the documentation for the DS3231 library. That arduino page points to the actual documentation by the library author where the basic usage is described:
