Countries with extensive territories or overseas dependencies span multiple time zones. The United Kingdom, due to its overseas territories like the Falkland Islands and Pitcairn Islands, observes several time zones. Similarly, France, which is not listed but is a good example, has many time zones due to its overseas departments and territories. Australia also uses multiple time zones across its mainland and external territories. Brazil, while large, is largely consolidated within fewer time zones. New Zealand primarily uses one time zone but has dependencies. Denmark, through Greenland, also accounts for multiple time zones.
