C++ error LNK2019

I need to create string variable string time and it should look like 14:58.
I created function 

string SetTime() {
long double h = (long double)(rand()%25);
long double m = (long double)(rand()%60);

string hour = to_string(h);
string minutes = (m <= 9 ? "0" : "" ) + to_string(m);

string time = hour + ":" + minutes;
return time;
}

but when I try to use it

string str = SetNumber();
cout << str;

I get
error LNK2019: link to unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl SetNumber(void)" (?SetNumber@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@XZ) in _wmain

What's wrong and how to fix it?

Your function is called SetTime while you're calling SetNumber. The linker cannot find the definition of SetNumber. It is interesting that you are getting a linker error rather than a compiler error. It means that you've declared SetNumber.
