Brazil abolished daytime change a couple of years ago. Our time is the same all year, no more +1 and then -1 hour.

It was mess on the day there should a change, many people arrived on their appointments one hour before or later. Many automatic systems changed their time, different clocks at home reported different hours.

This chaos lasted one morning. After some time, nobody now complains about not having it. Many people don't remember about the change anymore. The only people that complains about daylight change are the ones that work with people from countries that have that.

Abolishing daytime change is not the same as adopting an "universal" (country-like?) timezone, but shows that it is _possible_ to do on a "big country spanning a lot of latitude as well as longitude and tens of millions on wildly different work and sleep schedules".

Maybe the main issue is that many people fear change? (Which is quite "funny", as winter/summer time is a change in time...)
