After Benjamin Linus moved the Island ("There's No Place Like Home, Part 2"), a number of characters, mostly survivors of Flight 815, began experiencing a phenomenon wherein they would suddenly be transported to another point in time in the Island's history. The only warning the characters experienced that such an event was imminent was a distant ringing noise that would quickly build in intensity, culminating in a bright flash of white light as the transportation took place. The term time flash has been coined to describe this event.
