more wrinkled time

Liz B brought up the question of L'engle's confused timelines. I have actually seen a timeline in some more recent editions of L'Engle, which is actually two timelines -- does anyone remember what they were called? One was Kronos, I think, the other Kairos? Anyway -- the idea was that some characters live in normally progressing time and others live in a non-standard timeline, and that explains the Zachary Grey confusion.

Yes, it was kronos and kairos - what would we do without google?
