Europe is also interesting, but the other way around. Most of mainland Europe is on the Central European Timezone (UTC+1), despite the difference in solar time between western Spain and eastern Poland being about 2 hours. Solar time wise western spain should be at ~UTC-0:40, and eastern poland at ~UTC+1:30
