That stupid "special" timezones in Canada messed up Microsoft (they got their issues for not keeping their record stragith).
This is what happens when a part of country does not follow. China is the other extreme. They got one stupid timezone, so one part of the country is dark AF, but then other side is daylight.
This all comes down to whoever is running the government.
US should also abolish stupid daylight savings, but northern politicians do not want while there is bipartisan agreement to make the savings time permenant.
