🌍 Some Antarctic research stations use New Zealand’s time zone, while others choose the time of their home country. This means clocks at the South Pole can show different times—sometimes up to 12 hours apart. ✨ #timezones⚡#antarctica⚡#clocks⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels
