This is most likely an issue in the timezone handling, in the underlying Rust core (specifically, this is an exception that is thrown by the `chrono` crate when `unwrap`ing a `LocalResult`).

Can you provide more detail? Did the error occur when you tried to open the card info screen? Is it reproducible? Is it a certain card causing it?

I haven’t tried to reproduce it since then. I just got a message like that while I was reviewing my card.

If further errors occur after that, I’ll let you know right away.

thank you.
