Is there any way to get frame count of timeline animation using JSX script?

I want to extract frame count using JSX script?
I have used following code. But it seems not sharp as expected (In case of decimal point of seconds it seems not good)

function getTimelineLength() {

var ref = new ActionReference();

ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('duration'));

ref.putClass(stringIDToTypeID('timeline'));

var desc = new ActionDescriptor();

desc.putReference(charIDToTypeID('null'), ref);

var TC = executeAction(charIDToTypeID('getd'), desc, DialogModes.NO);

TC = TC.getObjectValue(stringIDToTypeID('duration'));

var M = 0;

try { M = TC.getInteger(stringIDToTypeID('minutes')); } catch (e) { }

var S = 0;

try { S = TC.getInteger(stringIDToTypeID('seconds')); } catch (e) { }

var F = TC.getInteger(stringIDToTypeID('frame'));

var FR = TC.getInteger(stringIDToTypeID('frameRate'));

var A = new Array();

A.push([[M], [S], [F], [FR]]);

return A;

}

//option 1

var frameCount = timeLineInfo[0][2] ( But this returns "0" value with newly opened document)

//option 2

var timeLineInfo = getTimelineLength()

var frameCount = timeLineInfo[0][1] * timeLineInfo[0][3] ( This is not returns correct value with decimal value of seconds )

Anyone have a better solution?

Correct answer r-bin

var r = new ActionReference();

r.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('frameCount'));

r.putClass(stringIDToTypeID('timeline'));

var ret = executeActionGet(r);

alert( ret.getInteger(stringIDToTypeID('frameCount')) );

//

Legend

var r = new ActionReference();

r.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('frameCount'));

r.putClass(stringIDToTypeID('timeline'));

var ret = executeActionGet(r);

alert( ret.getInteger(stringIDToTypeID('frameCount')) );

Apologies for delay, I must have missed the email.
@schroef You put me on the right track, thanks! I had to swap out "timeline" for "animationClass" and now it works:

var r = new ActionReference();
r.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('frameCount'));
r.putClass(stringIDToTypeID('animationClass'));
var ret = executeActionGet(r);
alert( ret.getInteger(stringIDToTypeID('frameCount')) );

So that's working, but I'm still not seeing a way to get a frame animation frame's duration. The duration mentioned above seems to be for video clips maybe, as it throws an error when I try it with a frame animation.

Is there a way to get those? For instance, from the attached PSD, I'd like to in the end get `[1,0.2,0.2,0.2,0.2,1]`

// determine durations in a frame animation;
// 2024, use it at your own risk;
if (app.documents.length > 0) {
var myDocument = app.activeDocument;
var theNumbers = new Array;
var theCounter = 1;
var theCheck = selectFrame (theCounter);
//var theFrameCount = GetFrameCount();
while (theCheck != false) {
var theDur = getFrameDelay(theCounter);
theCounter++;
theNumbers.push(theDur);
var theCheck = selectFrame (theCounter);
};
alert ("durations\n"+theNumbers.join("\n"))
};
