User blog:Station7/What does this mean? Please with picture :)

Hey there, on Day 3: 1:00pm-2:00pm there is at the Background information and notes this said:

''This episode marks the first time that someone tints the windows of one of the offices at CTU. The second time this happens is in Day 8: 12:00pm-1:00pm.''

What does this mean? It's strange that I didn't asked this before, but I really want to know what this does mean. :) Please so, with picture. :D --Station7 (talk) 22:41, November 6, 2016 (UTC)
