My current job often challenge me with various country codes and timezones. So I prepared two lists providing you with this information. country_codes.csv list all country codes (ICAO, ISO 2-letter, ISO 3-letter, ISO 3-digit), country names and continents. timezones.csv will list the ISO 2-letter code together with country name and Unix Timezone. Both lists might not be complete. So if you find errors or omissions, just let me know.
