As a user I would like to view all times as 24-hour time as is common in my country (Finland).

On a personal note: I have never internalized the difference between 12AM and 12PM and I probably never will, it's very confusing because, to me, its meaning is a coin-toss.

Another part of this request is to stay consistent with the selection. All time should be formatted via a specific function that takes the user selection into account. In the screenshot below you can see that the notice is in 24-hour time and the inputs are 12-hour.
