There's a lot of pressure, in every modern democracy, to have the timezone at least not behind the sun. It's so easy to sleep in, I guess, and so those of us stuck inside during working hours want at least some leisure time outside.

For people at the western edge of the timezone, it's fine, because they're advanced compared to the sun by design. For people at the eastern edge of a timezone, they're somewhat behind the sun by design. So in much of Europe and the US, countries/states/counties that should be in timezone X are in timezone X+1. Spain is a leading example of that, but even France should be in GMT. And everywhere that uses daylight savings is an example for at least half the year, some are double examples.

In effect, the error is the decision that timezones should be centred rather than east-aligned.
