summon monster with delay

[Gsp]

hello guys
this is my movement script
it summons monsters on stepin

 wl1 = {x=212, y=225, z=10}
 wl2 = {x=208, y=224, z=10}

function onStepIn(cid, item, frompos, item2, topos)
     if getPlayerStorageValue(cid,15321) == -1 then

doSummonCreature("Warlock", wl1)
doSummonCreature("Warlock", wl2)
		setPlayerStorageValue(cid,15321,1)
end
return 1
end

how do i make it so it will summon 2 more warlocks after 30 seconds? im still learning .i think addEvent is used for this. i tried but its beyond my knowladge. hope someone helps so i can learn addevent function and have a nice quest script for my server
thanks

function onStepIn(cid, item, frompos, item2, topos)
 local time =
{
   sec = 30
}
	if getPlayerStorageValue(cid, 15321) == -1 then
	   doSummonCreature("Warlock", {x=212, y=225, z=10})
	   addEvent(funcSummonWarlock, time.sec * 1000)
	   setPlayerStorageValue(cid, 15321, 1)
 end
 return TRUE
end

function funcSummonWarlock()
	   doSummonCreature("Warlock", {x=208, y=224, z=10})

Yeah:

				function onUse(cid, item, fromPosition, itemEx, toPosition)
 local time =
{
   sec = 30
}
	if getPlayerStorageValue(cid, 15321) == -1 then
	   doSummonCreature("Warlock", {x=212, y=225, z=10})
	   addEvent(funcSummonWarlock, time.sec * 1000)
	   setPlayerStorageValue(cid, 15321, 1)
 end
 return TRUE
end

function funcSummonWarlock()
	   doSummonCreature("Warlock", {x=208, y=224, z=10})
 return TRUE
end
