That's a cultural issue, and Spain has only one time zone anyway. A lot of business can be conducted across the United States, which is fairly consistent in its hours. I suspect that Russia is fairly consistent within their borders as well.

The cultural issue is the entire point here, so it can't really be brushed away. The idea that pretty much any list of things could be true worldwide falls down rather quickly.

(PS Spain has multiple timezones: http://www.timeanddate.com/worldclock/city.html?n=141 vs http://www.timeanddate.com/worldclock/city.html?n=683 for example)
