The island was claimed by the United States pursuant to the Guano Islands Act as were the other three islands of Tokelau, which claims were ceded to Tokelau by treaty in 1979. In the draft constitution of Tokelau subject to the Tokelauan self-determination referendum in 2006, Olohega is claimed as part of Tokelau, a claim surrendered in the same 1979 treaty which established a boundary between American Samoa and Tokelau.Tokelau's claim to Swains is generally comparable to the Marshall Islands' claim to US-administered Wake Island, but the re-emergence of this somewhat dormant issue has been an unintended result of the United Nations' recent efforts to promote decolonization in Tokelau. Basically, Tokelauans have proved somewhat reluctant to push their national identity in the political realm: recent decolonization moves have mainly been driven from outside for ideological reasons. But at the same time, Tokelauans are reluctant to disown their common cultural identity with Swains Islanders who speak their language. Tokelau is in a different time zone from most of New Zealand, being 10 hours behind Coordinated Universal Time (UTC) rather than 12 hours in front, meaning a 22 hour time difference for much of the year (New Zealand has daylight saving time (DST) for part of the year while Tokelau never participates). Tokelau is in the same time zone as the Cook Islands and Hawaii rather than neighbouring Samoa and American Samoa. - - Geographic locations of Tokelau's atolls
