Clocks didn't flip over to BST?

@MaBe: I think you underestimate the complexities of internation summer time rules. First for the southern hemisphere the changes should be otherway round. Second the change dates vary wildly. Third, not always 1 hour, there are also eg 2 hour changes.

Wow, I definitely did, thanks for your clarification.

I guess that could be added to the bootloader?

First I thought firmware is a good place, so all devices can benefit from this, but why not bootloader, other board can have a bootloader too :) .
