  * \note mbedtls_platform_gmtime_r() is an abstraction in platform_util.h that
- * behaves similarly to the gmtime() function from the C standard,
- * but is thread-safe. Mbed TLS will try to identify the underlying platform
- * and configure an appropriate underlying implementation (e.g. gmtime_r() for
- * POSIX and gmtime_s() for Windows). If this is not possible, then
