Kinda like the old APF timer except for the gauntlet instance. Also that it can capture the global "Gauntlet will soon be open" and set its timer automatically.

After the Gauntlet announcement comes the portal mob spawns and has 10min grace, since there is 100+ people always there he dies within a few seconds and the portal opens. Thats what you wanted to know?

Actually 10 min is what FC said it would be, but it looks like it might be a little shorter, but that will be easy to change if it happens to be shorter. If rest of the code is there ^^
Someone from org also requested that you can sign up on a notify list for it and when its say 30 and 10 min left to pop you get a PM warning.

Another thing would be to see the timer and the actual time the next three portals will spawn at and that these 3 update with every global announcement.

Looking forward to see how it turns out!
