Well Spain's time is a bit weird because they use CET which is most appropriate for like Sweden and the Czech Republic and the countries slightly east or west of them. Even France's use of CET is more about integration with their eastern neighbors than about having the sun the highest at 12 pm.
A JPL intern from Spain basically told me that the day end when sunset in Spain, it's very easy there. In California sunset can be around 5 pm and that's too weird for her. From the a quick google look, it seems like Spain daylight start from 6am or 7am and end around 8 or 9 pm. It's super interesting.
