I’m not sure what you’re after exactly, but here’s a clock expression (for a text layer’s source text) that might help:

beginTime = 0; // beginning time (seconds)
mult = 1; // clock speed multiplier

function digits(myVal,myNumDigits){
  var s = myVal.toString();
  while (s.length < myNumDigits) s = '0' + s;
  return s;
}

currTime = beginTime + time*mult;

hr = digits(Math.floor(currTime/3600),2);
min = digits(Math.floor((currTime%3600)/60),2);
sec = digits(Math.floor(currTime)%60,2);
ms = digits(Math.floor(currTime%1*1000),3);
hr + ":" + min + ":" + sec + "." + ms

If you want it to start at a time other than 0, set beginTime.
If you want it to count faster or slower than comp time, modify mult.
(mult = -1 will count down).

If you want to wiggle just x and leave y alone you could do it this way:

freq = 7;
amp = 50;
w = wiggle(freq,amp);
[w[0],value[1]]

If you want to wiggle both x and y but with different parameters, you could do it like this:

xFreq = 7;
xAmp = 50;
yFreq = 3;
yAmp = 100;
wX = wiggle(xFreq,xAmp);
wY = wiggle(yFreq,yAmp);
[wX[0],wY[1]]

In expressions, color is represented as an array of [red,green,blue,alpha] where the values have to be between 0 and 1. (Leave the alpha value set to 1 – it doesn’t do anything but it has to be there. So this would be one way to change the color at random every half second:

period = 0.5; // change color every .5 seconds
colors = [[1,0,0,1], // red
          [0,1,0,1], // green
          [0,0,1,1], // blue
          [1,0,1,1], // magenta
          [1,1,0,1], // yellow
          [0,1,1,1]] // cyan

seed = Math.floor(time/period);
seedRandom(seed,true);
idx = Math.floor(random(colors.length));
colors[idx]

That is strange indeed. You might want to drop a line to aebugs@adobe.com.

How about just using the wiggle expression?

First set the value of the parameter to the middle of the range you want and then add an expression like this:

freq = 1.0; //frequency = once per second
amp = 20; // amplitude = -20 to +20
wiggle(freq,amp)

If, for example, you set the value of your parameter to 60 and then added the above expression, your parameter would vary between 40 and 80.
