Rez Timer

Hey there!I'm making a comet rezzer and for the rezzing object itself, right now it's set to rez the comet when I click the rezzer. I'd like to change it to rez every 60 seconds or so, all on it's own. I've looked into the timing but I'm completely stumped. Any help is greatly apprecited! Here's what I've got:

default
{
touch_start(integer dix)
{
integer i;
vector pos = llGetPos() + <0,0,10>;

for (i = 0; i < 1; i++)
{
llRezObject("comet", pos, ZERO_VECTOR, ZERO_ROTATION, 1);
}

llResetScript();
}
}

The example should tell everything you need to know about timers. What else can I say?
