Weird date bug - date gets registered as one day before what I input

Hello,

I have the weirdest bug and I don’t know where to start from to debug it.
When I input a date metadata, then the date is saved as one day before what I input (example 20/10/2020 becomes 19/10/2020). This happens both when I create a new item, and when I edit the date metadata of an existing item.

Thanks for the help
