Any part of a day in the Schengen side/area eats up a day for the purposes of the 90 day limit. So if you clear Schengen entry passport at 11pm today and do Schengen exit passport control two hours later, it counts as two days for this purpose.

France — at CDG at least — has usually been pretty relaxed from what I’ve observed for US, UK, Canadian, Australian and NZ passport users at passport control even when with pages chock full of Schengen stamps. Swedish passport control, however, has been more aggressive about UK passport users than Danish passport control — when it comes to those with UK passports full of Schengen stamps but no documentation allowing stays longer than 90 days in any given 180 day period.
