Oh, that was a fun one!  Let's do it again!  That thread involved 
not only motivation of characters but detailed research on official 
sunrise/sunset.  Did anyone ever send a final time line to Lexicon 
Steve?

Here are two of the posts:
Pippin pro Snape: 107919
Neri anti Snape: 108037

IIRC Neri's post sums up the time, while Pippin's post discusses 
motivation. But there are lots of posts on this tread.
