So Ben “moved” the island, how about that. First lets go back to episode 9 “The Shape of Thing to Come”, remember that Ben wakes up in the middle of the Sahara Desert (presumably in Tunisia) wearing that jacket with the Orchid station emblem, and the name Halliwax on it, and with a cut on his right arm. When he arrives at the hotel in Tunisia he asks what the date is… its October 21st 2005. Right, ok.
Ben told Locke that whoever moved the island couldn’t come back. He didn’t say anything about traveling over 10 months into the future at the same time. When Ben ‘moves’ the Island its around day 100-101, which would be around New Year’s Day 2005. It seems pretty straight-forward that Ben ends up in the Sahara as a direct result of moving the Island, especially since he’s still got the cut on the arm (from when he fell down the ladder), and he’s wearing the jacket with the same name on it.
