I always figured it was a matter of perception. They need TARDISes and other technology to actually change anything, but their limited telepathic abilities, combined with other extrasensory hints like being able to feel the rotation of a planet and their mad multi-tasking skillz suggests to me that they may be a bit like Jedi, but with time instead of the Force. I don't think they exist OUTSIDE time so much as they are just hyper-aware of time and are quite adept at fine-tuning their - and others' - perceptions. They were then able to manufacture technology that matched, then exceeded their own time sensing abilities.

*shrug*

That's my view of it, anyway.
