+
+            After enabling RT_LIBC_USING_FULL_TZ_DST, the project will automatically import the tz_database code and data files.

+            RT_LIBC_USING_LIGHT_TZ_DST is a lightweight timezone and daylight saving time configuration option within the C standard library (libc) component of RT-Thread.
+            It is a lightweight alternative to RT_LIBC_USING_FULL_TZ_DST (the full timezone solution).
+
+            It achieves local timezone conversion using a fixed time offset, rather than relying on a large timezone database.
+
+            This option is enabled by default, but only one of RT_LIBC_USING_FULL_TZ_DST can be enabled at a time.
+            When enabled, three sub-configuration options will be displayed.

+    help
+        RT_USING_CPLUSPLUS is the master switch for enabling C++ support.
+
+        It is off by default. Once enabled, RT-Thread's build system ensures that a C++ compiler is used to compile .cpp files,
+        and it links C++ standard libraries (such as libstdc++ or libc++) into the final firmware.
+        Other C++-related configuration items that depend on it become visible and configurable.

+            RT_USING_CPP_EXCEPTIONS is used to enable C++ exception handling.
 
+            It is disabled by default. Enabling this option pulls in the C++ exception runtime support, which typically increases
+            code size (flash/ROM usage), RAM consumption, and may add extra runtime overhead for stack unwinding and exception
+            bookkeeping. On resource-constrained or strict real-time systems, this additional overhead should be evaluated carefully
+            before turning the option on.
