-- The :flag:`NativeCompute Timing` flag causes calls to
-  :tacn:`native_compute` (as well as kernel calls to the native
-  compiler) to emit separate timing information about compilation,
-  execution, and reification.  It replaces the timing information
-  previously emitted when the `-debug` flag was set, and allows more
-  fine-grained timing of the native compiler (`#11023
-  <https://github.com/coq/coq/pull/11023>`_, by Jason Gross).

+- **Changed:** The :flag:`NativeCompute Timing` flag causes calls to
+  :tacn:`native_compute` (as well as kernel calls to the native
+  compiler) to emit separate timing information about conversion to
+  native code, compilation, execution, and reification.  It replaces

+  set, and allows more fine-grained timing of the native compiler
+  (`#11025 <https://github.com/coq/coq/pull/11025>`_, by Jason Gross).
+  Additionally, the timing information now uses real time rather than
+  user time (Fixes `#11962

    .. flag:: NativeCompute Timing
 
       This flag causes all calls to the native compiler to print
-      timing information for the compilation, execution, and
-      reification phases of native compilation.
+      timing information for the conversion to native code,
