Why is there an #OpenStreetMap changeset covering a huge swath of North and South America?

Because we have timezone relations now for some reason.

Why? Why do we have these? They're terrible.

Version 207 and my browser won't even load the history because the website times out. I need to check JOSM to see that it's only 2 years old. On average each version lasts less than 4 days.

If we have to have this data, surely there's a better way?
