            If set, then the app will be built with the current time/date stamp. It is stored in the app description
            structure. If not set, time/date stamp will be excluded from app image. This can be useful for getting the
            same binary image files made from the same source, but at different times.

            The PROJECT_VER variable from the build system will not affect the firmware image.
            This value will not be contained in the esp_app_desc structure.

            The PROJECT_NAME variable from the build system will not affect the firmware image.

            If this is enabled, then config item APP_PROJECT_VER will be used for the variable PROJECT_VER.
            Other ways to set PROJECT_VER will be ignored.

        help
            At startup, the app will read the embedded APP ELF SHA-256 hash value from flash
            and convert it into a string and store it in a RAM buffer.
            This ensures the panic handler and core dump will be able to print this string
            even when cache is disabled.
            The size of the buffer is APP_RETRIEVE_LEN_ELF_SHA plus the null terminator.
            Changing this value will change the size of this buffer, in bytes.
