To be sure, if there is no badge again, I will make a test purchase one hour later at the 'real' 4:20 pm PST (= UTC-8h, like the description of the badge), if the server scripts are actually programmed on PST. That would be 0:20 UTC/GMT = 2:20CEST.
The achievement description (in french) now talk about...buying a card at 23h20 GMT (was 16h20 GMT two days ago)
so it's 19h20 eastern time, here in Quebec. (01h20 am in Paris)
so, i will try ...unless i forget.
BUT if it really need to be 23h20min,and 00 sec, you need to be lucky.
i don't really care about achievement, on my Xbox, why did i care about this achievement here ?
