Prior to the school fire, a caption says "Paris 1925". Upon his arrest as an adult, Abel, through his narration, remembers the fire as having happened "twenty years ago". This would place his adult scenes in 1945, but when he joins the French army after his arrest it is before the German occupation of Paris which would place his arrest in 1940. However, Abel is slow-witted and possibly does not have an accurate sense of time.
