Can I solve "returning address of local variable or temporary" without changing other functions in the code?

Question

When running the following code I get the error:

returning address of local variable or temporary

trying to solve the issue my idea was to change n_date to:

char* n_date = (char*)malloc(sizeof(char) * 60);

However, since I am not allowed to modify the function output_fun, with declaring n_date as a char* I get the error

Compile error c2664 'function' : cannot convert argument n from 'type1' to 'type2'

what could be a solution to this problem?

const char* funA(const char* input)
{
    struct tm date;
    char n_date[60];
    strftime(n_date, 80, "%B %d, %Y", &date);
    ouput_fun(n_date);
    return (const char*)&n_date;
}
