ocean_soul writes "Starting January 1, 2012 Samoa and Tokelau will be in time zone +13 instead of -11. This means there will be no December 30, 2011 in these countries. The decision to switch time zone was based on the changing international business relations of Samoa. Samoa had adopted the -11 time zone to make business with the U.S. easier. However, currently Samoa's most important trading partners are Australia and New Zealand. By switching time zone the work-weeks and week-ends on Samoa and Tokelau will be synchronized with those in Australia and New Zealand."
