I average out the spring and fall changes and just set my clocks 39 minutes ahead year-round.
International travel would be way more confusing.
If I land somewhere at 9am local time I know that the bank will be open when I land and it will be day time.
If everyone is on the same time and I travel somewhere it will be a complete surprise (or I will have to figure it out before hand) whether or not it will be the middle of the night or the middle of the day.
