asynchronous time handler : Kernel mode

hello ,

i want to ask how can i set time event on a click element in KERNEL mode,

for example i have created an element : myElement

prevElement()-> myElement() ->nextElement();


in  myElement, i'm receiving some special packets , for each packet i 
need to hold some info like dst ip,  currentTime,
so i have an array :  myarray.add(p->ip, getCurrentSystemTime, 
time_threshold, false) ;
and then I forward the packet .


in this point , for each value  in the array i want to set an event :

if (  myarray[index].getTime()+myarray[index].getThreshold >= 
getCurrentTime()  )   THEN

              CALL expirefunction()


int expirefunction(){

// do something
}


Any idea someone how to add this event in my element?
