+# Instance of Timer Library only using CPU resources.
+#
+# Timer Library that only uses CPU resources to provide calibrated delays
+# on IA-32, x64, and IPF.
+# Note: Because CPU Local APIC and ITC 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.
+#
+# This library differs with the SecPeiDxeTimerLibCpu library in the MdePkg in
+# that it uses the local APIC library so that it supports x2APIC mode.
