I don't think that changing the time zone is going to make any productivity or 'family time' change. We work a lot of hours because there are more employees than companies. Market laws.

I think, however, that changing the time zone will improve our reputation. Currently we're at sync with sun time, but from the point of view of a tourist it means that we have lunch, get out of work, have dinner and go to bed at least 1 hour later than on 'normal countries', and this contributes to the fame of 'lazy country'.

Once we change the hour, after a period of adaptation, we will do everything pretty much the same but S&P will come an say... hey! look at Spain, now they deserve credit because they go to bed earlier, we should lend them money!.

Finally, we currently go into work at 9 as everyone else, but for us the sun is at 8. Nobody realizes because we have more sun hours (in winter).
