+#X text 90 234 [realtime] works like essentially like a stop-watch.
+Once it starts \, you can continue to "poll" [realtime] to view the
+elapsed time.;
+#X text 90 281 The odd aspect about comparing [realtime] to a stop-watch
+is that a stop-watch can be stopped! [realtime] can only be started
+or reset. It cannot be stopped.;
+#N canvas 108 160 428 429 About_clocks 0;
+#X text 20 60 In a fantasy world \, computers could exist somehow beyond
+the restrictions of time and digital computation could be performed
+in ZERO time. However \, that is not the case. Instead \, every process
+within Pd and within your operating system requires at least a few
+nanoseconds of your CPU's time.;
+#X text 21 145 The [timer] object is like a clock that is not constrained
+to the regular laws of physics and the universal space-time continuum.
+It reports "time" measurements as only Pd can see them!;
+#X text 22 205 The [cputime] object is like a clock that measures how
+much time your CPU actually required to carry out your request. Keep
+in mind however that your CPU is busy doing many things simoultaneously
+\, so even though a process might take 5 minutes to complete \, your
+CPU does not pay full attention to that process for the entire 5 minutes.
+Instead \, it simply begins the process \, then refers back to that
+process from time to time until the it is complete. In other cases
+\, your CPU might require a full 5 minutes while Pd might report that
+merely a few milliseconds have passed. This type of discrepancy depends
+heavily on your computer's hardware and the type of processing it is
+performing.;
+#X text 21 369 The [realtime] object is as much like your own wrist
+watch as Pd can possibly manage. It measures time according to your
+operating system's internal clock.;
