Spain is a good example of a politically-motivated time zone. Prior to Franco putting the country in CET to be in line with Axis powers, it was in GMT, which makes a lot more natural sense.

This defeats the purpose of having time zones at all. People generally prefer the sun near overhead at noon; otherwise we would all just set our clocks to UTC no matter where we are. It would certainly make programmers' lives easier ;-)
