To me "one thousand years" is just the script-writers way of saying "Once Upon a Time..." whilst trying to make it sound like there's some kind of chronology to the show.

FWIW, the only 'one thousand years' I think is set in stone is the first advent of Nightmare Moon. Beyond that, it's 'over one thousand years ago' in my headcanon.
