I would say that it would be 11am PST, ACME is located in Burbank, CA so that would be 12 noon my time.
Hemish, depending on your location I'm not sure of the time in Australia but I think it's Saturday, November 8, 2008 at 5:00:00 am for you. I'm guessing you are around the Brisbane area?

At this time, I am not sure what the limit is on this key. If the limit is one then set the clock so you can grab one as it is limited to 1000 as this one is sure to fly. Razor's Edge Collectibles
may carry this key as they have done in the past but still I am unsure at this time.
