here is the CLOCKFACE script...coded in 3 MINUTES...17 LINES of CODE

[Dennis Brown]

That is a good point.  I tested it out, and the useless "set angle"  
results in about 70ms of wasted time every second (7% CPU).  I am  
surprised it is so high.  Doing the test and skipping it is a  
thousand times faster.  I fixed up the script as my own exercise for  
the student.  You can see the time lag slightly when the computer is  
busy with something else, like loading a web page.

Note: the angle calculations had to be changed to match what the  
angle returned for these graphics.  The clock is in  my user space  
(see3d).  It takes a licking, but keeps on ticking...

on openCard
   setTime
end openCard

on setTime
   set the itemDelimiter to ":"
   put word 1 of the long time into T --8:13:15
   put T & char 2 to 5 of (the long seconds mod 1) into fld "Time"
   get 360+90-(30 * item 1 of T) - trunc((item 2 of T) / 2)
   if (the angle of grc "Hour") <> it then set the angle of grc  
"Hour" to it
   get 360+90-(6 * item 2 of T) - trunc((item 3 of T) / 10)
   if (the angle of grc "Minute") <> it then set the angle of grc  
"Minute" to it
   set the angle of grc "Second" to 360+90-(6 * item 3 of T)
   send "setTime" to me in 1-(the long seconds mod 1) seconds
end setTime
