About US time zones
Time in the United States is divided into nine standard time zones, with most of the United States observing daylight saving time for part of the year. Time zones are: Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (SST) and Chamorro Standard Time (ChST).
Note: Daylight Saving Time begins on March 13, 2011, and returns again to Standard Time on November 6, 2011. Arizona and Hawaii use standard time throughout the year. However the Navajo Nation observes DST throughout its entire territory, including the portion that lies in Arizona. But the Hopi Nation, which is entirely surrounded by the Navajo Nation, does not observe DST.
