This move made Caroline Island both the easternmost land in the earliest time zone (by some definitions, the easternmost point on Earth), and one of the first points of land which would see sunrise on January 1, 2000 — at 5:43 a.m., as measured by local time.
WikipediaThe Line Islands, Teraina Islands or Equatorial Islands (in Gilbertese, Aono Raina) are a chain of atolls (with partially or fully enclosed lagoons) and coral islands (with a surrounding reef). Kingman Reef is largely submerged and Filippo Reef is shown on some maps, although its existence is doubted. The islands were formed by volcanic activity and are located in the central Pacific Ocean, south of the Hawaiian Islands. The 11 islands stretch for 2,350 kilometres (1,460 miles) in a northwest–southeast direction, making it one of the longest island chains of the world. Eight of the islands form part of Kiribati, while the remaining three (Kingman Reef, Palmyra Island and Jarvis Island) are United States territories grouped with the United States Minor Outlying Islands. Only Kiritimati and Tabuaeran atolls and Teraina Island have a permanent population.
