+take advantage of this clock source to detect time jumps reliably. This
+will usually slow down EV a tiny amount, but this is usually
+well-invested. Unfortunately, some systems are bound to be broken, so
+you can disable this here. Whatever your reasons, you can completely

+compile- and runtime.
