I'm not really sure what you mean, changing the timezone of a country is certainly their prerogative and "technical experience" doesn't really have anything to do with it.
The EU is one example here but many other countries have timezone/DST changes, the EU is one of the places that don't change timezones often. The US on the other hand has such variety in timezones and DST observance, not even following state borders, that it's a real pain to support.
