Whoa! This anime takes place in 2009-2010! (no joke)
In episode 4, The Sound of Waves (~ 11:00 mark), you can see the date of birth of Rosaly Hammond: August 2, 1994. Her age is 15. Do the math and the year for that time would be 2009-2010.
I don't know about you guys but that's pretty amazing. Although I have heard that dates and these things are usually messed up by the the creators and writers...
