Extend Time To Complete Daily Emissary By 12 Hours!

[AggressionWoW]

I'd like to mention I play on Illidan US and this is extremely easy to do. It consists of setting the clock on your computer to the opposite of either (AM or PM). At the time of writing this it is 11:30 PM CST UTC -6 2/7/17, while my computer is set to 11:30 AM of 2/7/17. This isn't an exploit really but it allows more time for world quests for Emissary daily. I'm guessing this confuses the game to think I'm just hours behind, sort of like how in some apps on your iPhone and what not you change the time to override wait times.
Here's proof:
Imgur: The most awesome images on the Internet - the PM screenshot, shows 9 hours (located in the bottom right of my UI, on the right chat window).
Imgur: The most awesome images on the Internet - the AM screenshot, shows 21 hours, my clock shows the AM symbol this time.

Don't believe me? Try it yourself, after all it's easy!

I'd also like to add my Emissary expires at 12 hours later than normal at 9 PM CST instead of 9 AM CST on the same day, so I'm guessing it would be 7 PM PST, 8 PM Mountain, and 10 PM EST.

12 hours? I extended it by 49706 days. Screenshot by Lightshot
It stayed like that after couple of relogs aswell.

49706 days = 4294598400 seconds, 2^32 is 4294967296, meaning you overflowed the expiration timer by ~368896 seconds.

They most likely stack.
Edit: All active world quests also get extended to infinity. New ones are coming anyway until you have every WQ possible active.

This bit here is ridiculously exploitable.

Doesnt work with missions, I tried it, it extends to max but after you play a bit with time it resets to original time left.

It's not even that, it's the fact it's another example of how broken the server relying on the client is

so would it be possible to get new emmi wquests by setting the time foward if you done al 3 of them then?

What else can you do with it? What happens when you complete it and then set the time back, where you havent completed it?

Well its a proof that a tooltip is bugged, a real proof would be a new screen now that the emmissary should be over on US.

You could probably do quite a lot with it tbh. Can't really think of examples but will defo have a play; the fact the client/server use the system clock for that specific interaction is funny AF tho.

Your internet browsers had the same licensing problem as your wow client "so hotfixed". What is this, first line support? Just change your clock back and change it again after logging in.
