EDIT : It seems like the problem has been solved. I will suppose that this message has been seen by someone from Nintendo, so, thanks !
Original post :
I’m unofficially using Nintendo of Europe’s website API to get data from the games I’m playing, and I’ve noticed that an update made recently has caused many games from the database to get their releases dates edited, probably because of an error in timezones managing.
For example, The Legend Of Zelda : Breath Of The Wild real release date is March 3rd, [but on the website, it now appears to be March 2nd](https://www.nintendo.co.uk/Games/Nintendo-Switch-games/The-Legend-of-Zelda-Breath-of-the-Wild-1173609.html). Almost all Nintendo first-party games and some third-party Nintendo Switch games suffer from this error.
So, be careful if you intend to use this specific data from the european database. There are already some errors in the API on other secondary fields, but the release date may be used in many unofficial projects.
