* \brief Platform-specific implementation of gmtime_r()
*
* The function is a thread-safe abstraction that behaves
* similarly to the gmtime_r() function from Unix/POSIX.
*
* Mbed TLS will try to identify the underlying platform and
* make use of an appropriate underlying implementation (e.g.
* gmtime_r() for POSIX and gmtime_s() for Windows). If this is
* not possible, then gmtime() will be used. In this case, calls
* from the library to gmtime() will be guarded by the mutex
* mbedtls_threading_gmtime_mutex if MBEDTLS_THREADING_C is
* enabled. It is recommended that calls from outside the library
* are also guarded by this mutex.
*
* If MBEDTLS_PLATFORM_GMTIME_R_ALT is defined, then Mbed TLS will
* unconditionally use the alternative implementation for
* mbedtls_platform_gmtime_r() supplied by the user at compile time.
*
* \param tt Pointer to an object containing time (in seconds) since the
* epoch to be converted
* \param tm_buf Pointer to an object where the results will be stored
*
* \return Pointer to an object of type struct tm on success, otherwise
* NULL
