The EU is running an informal on-line survey to assess the public’s views on possible changes to the current summertime arrangements. At present, Spain is on GMT+1 (hour) except in the Canary Islands which works on GMT, as do Portugal and the UK. The EU instructs all member nations to put clocks forward an hour during summertime, which lasts from the first Sunday in March until the last Sunday in October.
Debate on which time-zone Spain should lie in has raged for years. It was said that Franco changed the country to GMT+1 during World War II to align with Berlin, although it has since been suggested that General de Gaulle made the decision after the war in a bid to main peace in western Europe.
Geographically, Spain should be in the same time zone as the UK, Belgium, the Netherlands and a large part of France. Galicia in particular wants Spain to change because of its close ties to neighbouring Portugal. On the other hand, the Balearic Islands wants to move to Central European Time (GMT+1) year round and even suggests GMT+2 in summer to allow tourists as much sunshine as possible.
The EU says that the reasons for the introduction of the twice-yearly change are now obsolete and is inviting comments until August 14. Full details can be found at the website: https://ec.europa.eu/info/consultations/2018-summertime-arrangements_en
