History
Kiribati introduced a change for its eastern half on 31 December 1994, from time zones UTC−11:00 and UTC−10:00 to UTC+13:00 and UTC+14:00, to avoid having the country divided by the International Date Line.

Tonga has been on UTC+13:00 for many years. Daylight saving time was used in the southern summer seasons from October 1999 to January 2002, and from November 2016 to January 2017 (written 2017).

UTC+13:00 was used until 2009 as a daylight time (summer in Northern Hemisphere) in the easternmost parts of Russia (Chukotka and Kamchatka) that used Kamchatka Time.

At the end of 29 December 2011 (UTC−10:00), Samoa advanced its standard time from UTC−11:00 to UTC+13:00 (and its daylight saving time from UTC−10:00 to UTC+14:00), essentially moving the international date line to the other side of the country. Following Samoa's decision, Tokelau also simultaneously advanced its standard time (used without daylight saving time), from UTC−11:00 to UTC+13:00.
