Your English is still better than my French. :)

The manga does not say that the reason the Jaw Titan was able to transform is because the sun is rising. Transforming at night is an ability all the Nine Titans have. The current battle in Liberio (chapters 101-103) is taking place at night and everybody is transformed; Attack, Jaw, Beast, Cart, War Hammer, and later the Colossus.

It's dark, but there are lots of people outside for the festival and all these Titans are fighting. The Nine Titans don't need sunlight the same way as regular Titans.

The idea that the Beast Titan is special in that it can operate at night is nice, but the wiki only accepts information supported by official sources, such as the manga.
