Is the localtime s function supported in the GCC translator?

Good afternoon.

I mostly use Visual Studio, and for some time now Visual Studio has been insisting with maniacal persistence that everyone use localtime_s instead of localtime because of the vulnerability of localtime from use in multithreaded applications. In Visual Studio 2017, this warning has been upgraded to a compiler error.

Everything would be fine, but sometimes you need the code to be translated under GCC. So I decided to check if it is supported localtime_s in GCC. I took the GCC online translator http://cpp.sh/ and wrote the program:

// Example program
#include <iostream>
#include <string>
#include <time.h>

int main()
{

struct tm *ptr;
struct tm structtime;
time_t lt;
lt = time(NULL);

ptr = localtime(&lt);
printf(asctime(ptr));

ptr = localtime_s(&structtime,&lt);
printf(asctime(&structtime));

  std::string name;
  std::cout << "What is your name? ";
  getline (std::cin, name);
  std::cout << "Hello, " << name << "!\n";
}

When trying to translate in the line

ptr = localtime_s(&structtime,&lt);

The translator informed me that:

17:34: error: 'localtime_s' was not declared in this scope

Relevant questions:

1. Is localtime_s supported in GCC?
2. Maybe you need a different header, not time.h?

Thanks.

UPD1:

On other online GCC translators such as:

Localtime_s doesn't work either. Even if you define all the specified macros.
