Since Windows doesn't provide gmtime_r(3) and localtime_r(3), we're providing a compat version by using non-reentrant gmtime(3) and localtime(3) as backend. Then, we copy the returned data into the buffer. By doing that, in case of failure, we will dereference a NULL pointer returned by gmtime(3), and localtime(3), and we always return a valid pointer instead of NULL. Drop the memcpy(3) by using gmtime_s, and localtime_s as backend on Windows, and make sure we will return NULL in case of failure.
