Wallace Turner (1983年11月1日). “Alaska's four time zones now two”. The New York Times. http://www.nytimes.com/1983/11/01/us/alaska-s-four-time-zones-now-two.html?mcubz=32017年11月17日閲覧. "The big change was in Juneau, Ketchikan and Sitka, the major towns in southeast Alaska, where clocks shifted back two hours to Yukon time. After decades on Pacific time, this region will now be an hour earlier, as will Anchorage and Fairbanks, which formerly were two hours earlier than Pacific time."
