Spain has long been suspected to suffer from their timezone choice. I do remember reading about that problem before, and a fast Google search finds several articles discussing the issue. (For example https://www.theguardian.com/commentisfree/2017/feb/22/spania...)

Up to a certain point, countries adapt. For example, Germany and France are in the same timezone, but their schedule is shifted. This can be easily seen when looking at the TV schedules. In Germany, evening TV starts at 20:15 (the start of movies, ...). In France it's more like 21:00. When I lived there it was 20:50, but TF1 now seems to start at 21:05.

Similarly, schools and kindergardens are usually not at the same time.

This local shifting works more or less, but can't be stretched too far. Especially multinational companies have expectations that workers come in at certain times. This is the problem that Spain faces. (I couldn't easily check by how much Spanish are shifted as Spanish TV schedules don't seem to coordinated like in France or Germany).
