As a result of temporal interference by Sarah Connor, her son John, Miles Dyson, and the T-800 destroying Cyberdyne headquarters and all backups of the research in 1995, the date for Judgment day is moved back to here. Skynet is destined to go online a few days earlier on April 19, 2011 at 20:11.
There's about three more hours for this to happen on the West Coast. Two more days until Judgment Day. Good thing I have the day off, I guess I'll be draining the pool and making a makeshift bombshelter to protect the family.
