+#X text 188 38 This is a super-high-resolution version of the [realtime]
+class that does not look at the ordinary clock of the operating system
+\, and instead uses the clock tick of the CPU itself. However \, if
+you have a variable-clock CPU \, this will give you some kind of virtual
+time.;

+#X text 190 114 It's also possible that this has some other bugs related
+to scaling. However \, even if it gives you really weird values \,
+this object will give you very precise values in what is really the
+wrong scale.;
+#X text 192 171 if you are trying to measure real time with this \,
+you should disable any CPU energy saving that may change the CPU's
+clock speed. However \, if you want to measure CPU usage \, [tsctime]
+is the ONLY of the time-objects to allow you to measure CPU usage reliably
+while your clock speed changes.;
