+#X text 27 35 [cputime] works like essentially like a stop-watch. Once

+time.;
+#X text 27 82 The odd aspect about comparing [cputime] to a stop-watch
+is that a stop-watch can be stopped! [cputime] can only be started
+or reset. It cannot be stopped.;
+#X text 26 132 As stated above \, [cputime] measures "CPU" time. This
+value may be slightly different than "logical" time or "real" time.
+PD offers two objects which measure "logical" time and "real" time.
+See the reference documents for those objects for more information.

+#X text 21 37 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 22 122 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 23 181 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 24 350 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.;
