Color Timing: What is it?

[dbzgundam]

I noticed whenever I read reviews of remastered, or restored movies (Star Wars, the new DVD of The Matrix, Extended Editions of LOTR), they mention "color retiming" or "the colors have been retimed", or something of that manner...

I've just been wondering how that works, and for that matter, what it even is. It seems like just another term for color adjustments if anything, but if I'm wrong please correct me. :o

Also... If this could be done in any program (Photoshop, AVISynth, etc) TELL ME!:D
