It's a prime example of humanity being stuck in its old ways. During both World Wars, the Germans put Belgium to their timezone, UTC+1. Almost 70 years later, this still hasn't been changed. With as result that in the summer, we're two hours ahead of the correct time.
The Germans did the same with France (which is due south of England, and hence straddles the 0͏° of longitude), and yet it's on CET (central european time).
