+    <Description>Timer Library that only uses CPU resources to provide calibrated
+      delays on IA-32 and x64. Note: Because CpuLocalApci timer could be programmed
+      by OS, it cannot be used by SMM drivers and runtime drivers, ACPI timer is
+      recommended for SMM drivers and runtime drivers.</Description>
