+// huffware script: hour hand, modified by fred huffhines.
+// 
+// expanded to support time zones by fred huffhines, december 2009.
+//
+// noticed this in arcadia asylum's great hobo cuckoo clock.
+// this script is licensed by Beezle Warburton:
+//    "I released those 'into the wild' years ago,do what you like,
+//     I just ask that people don't resell the scripts by themselves."
+//
+// fred's changes licensed by:
+//   this script is licensed by the GPL v3 which is documented at: http://www.gnu.org/licenses/gpl.html
+//   do not use it in objects without fully realizing you are implicitly accepting that license.
+
+// Optional second hand will be a much simpler script that will be
+// unrelated to real-time.
+//
+// note - to reduce load, this script only calculates once a minute, so
+// this provides a jump style minute hand, rather than a smoothy rotating one.
+// This (and rounding) makes the clock's accuracy +/- 1 minute.
+// It's a prim clock anyways, so digital accuracy is just excessive.
+//
+// It would probably be more elegant to use link messages rather than each
+// hand having it's own script, however, this method allows for less caution
+// when linking/unlinking parts of the clock.
+
+// To not mess up timekeeping, please keep chime sounds under 4 seconds long.
