(1/6/2014 2:00:00 PM Pacific) - the date that represents the millisecond UNIX timestamp found in hunrath.com's source code. I think that thoughts on that date would be of some fun here, at least until we get more information.
My speculation is that on that date there will be GPS coordinates to locations around the planet that will result in more clues when visited physically. My reasoning is based on looking at "ARG"s like Cicada 3301 and others that had similar countdowns. The countdown gives a gap that allows the planning and placing of such clues. Logistics is a bear after all!

PS: Has anyone bothered to see if there are any hidden messages in the behind-the-scenes images posted to the Kickstarter?
