keyboard - How to remap a double click button in autohotkey

Question

I have a special mouse button that serves as a double click. It doesn't have any special key, it's just sending two LButton signals.

I have introduced the #InstallMouseHook into my script to be able to track mouse clicks. I have gotten this after pressing the double button multiple times:

VK  SC  Type    Up/Dn   Elapsed Key     
---------------------------------------------------------------------------------------     
04  000     d   2.78    MButton         
04  000     u   0.19    MButton         
01  000     d   0.65    LButton         <- Manual DC     
01  000     u   0.17    LButton         
01  000     d   0.11    LButton         
01  000     u   0.14    LButton         
04  000     d   0.75    MButton         
04  000     u   0.19    MButton         
01  000     d   0.45    LButton         <- Special button DC            
01  000     u   0.00    LButton         
01  000     d   0.00    LButton         
01  000     u   0.00    LButton

From what I assume The elapsed key is key to determining what is a double click (DC) by the DC mouse button and which one by me manually pressing left click two times. I want to remap the former scenario, not the latter (DC button::something else like middle click and my manual double left click to remain the same). So far it seems that the elapsed time for the DC button is <2.0 and manual DC >2.0.

The idea would be to have something like this (not in AHK language):

loop 
 if (LButton == 1) //pressed
    {
    t=StartElapseTimer;
    if (t<2 && LButton == 1) //how to check it went down and up before down the 2nd time?
       LButton::MButton; //the remapping I want
    else // t>2
       Nothing //let me do a regular DC
    }
end

Could you help me on how to start the timer and what environment variables need to be set?

Thanks.

I'm having a really hard time grasping what you're actually asking. Is it correct that you have some kind of special mouse button that generates double clicks and you want to remap this button? If yes, it would be great if you outlined these "special double clicks" in the above keylog, so that they can be told apart from normal (double) clicks. — MCL
Yes, that is exactly what I am trying to do. Added an intro paragraph to my question. — JonesR
Clarified in the keylog (all are from the special button except the last) — JonesR

Upon each click, you have to check the elapsed time since the last click and decide how to handle the information:

dcTime := 50

LButton::
    if(A_PriorHotkey = A_ThisHotkey && A_TimeSincePriorHotkey < dcTime) {
        Send, {MButton}
    } else {
        Send, {LButton}
    }
return

Of course, you'll have to adjust the timeout according to your mouse button's speed. I also recommend calling SetBatchLines, -1 as it will minimize inaccuracies in time measurement.
