You may want to start your 4/20 celcbrations a day early.  Skynet officially goes online at 20:11 tonight.  Of course if John and Sarah Connor (and Myles Dyson) were successful in their destruction of Cyberdyne back in 1995 we have a reprieve on Judgement Day until April 21st.  Too bad Judgement Day couldn’t come before they made the 3rd movie!
