The spanish public have already been shown to be massively in favor of staying on UTC+2 year-round, though this would mean that the sun wouldn't rise till 0930 in the depths of Winter.

I think once the government actually stops and takes a look at the repercussions of all options we will end up carrying on with the status quo.

If you want the sun to be at its high point at noon, Spain is obviously in the wrong time zone. But you see plenty of countries around the world choosing a slightly different timezone to facilitate trade and communication with some other country (or within itself, in the case of larger countries). With most other barriers to trade gone within the eurozone having to convert timezones is a significant inconvinience that (in the mind of many) outweighs having the sun in slightly the wrong place.
