Content:  mean solar time. All jurisdictions have adopted the UTC standard, starting on 1 September 2005. In Victoria, South Australia, Tasmania and the ACT, the starting and ending dates of daylight saving times are officially determined by proclamations, declarations, or regulation made by the State Governor or by the responsible minister. Such instruments may be valid for only the current year, and so this section generally only refers to the legislation. In New South Wales and Western Australia, the starting and ending dates, if any, are to be set by legislation. Western Standard Time (AWST) – UTC+08:00  Central Standard Time (ACST) – UTC+09:30  Eastern Standard Time (AEST) – UTC+10:00  
Title: Time in Mexico
Content:  Standard time was first defined in Mexico in 1922, when President Álvaro Obregón decreed two time zones. One time zone designated for 90° W (6 hours behind GMT) covered the states of Tabasco, Chiapas, Campeche, Yucatán, and Quintana Roo. A second time zone designated for 105° W (7 hours behind GMT) covered the rest of the country, from Baja California to Veracruz and Oaxaca. In 1930 three zones were decreed: Hora del Oeste (120° W, UTC−08:00) for the state of Baja California (norte); Hora del Golfo (90° W, UTC−06:00) covering the states of Tamaulipas, Veracruz, Oaxaca, Tabasco, Chiapas, Campeche, Yucatán and Quintana Roo; and Hora del Centro (105° W, UTC−07:00) for 
Title: Time in Australia
Content:  Australia uses three main time zones: Australian Western Standard Time (AWST; UTC+08:00), Australian Central Standard Time (ACST; UTC+09:30), and Australian Eastern Standard Time (AEST; UTC+10:00). Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones. Standard time was introduced in the 1890s when all of the Australian colonies adopted it. Before the switch to standard time zones, each local city or town was free to determine its local time, called local mean time. Now, Western Australia uses Western Standard Time; South Australia and the Northern Territory use Central Standard Time; while New South Wales, Queensland, Tasmania, Victoria, Jervis Bay Territory, and the Australian Capital Territory use Eastern Standard Time. Daylight saving time (+1 hour) is used in jurisdictions in the south and south-east: South Australia, New South Wales, Victoria, Tasmania, and the ACT. It is not currently used in Western Australia, the Northern Territory or Queensland. Norfolk Island has NFT (UTC+11:00; 1 hour ahead of AEST) and during summer has NFDT (UTC+12:00; 1 hour ahead of AEDT).
Title: Time in the United States
Content:  Standard time zones in the United States and other regions are currently defined at the federal level by law 15 USC §260. The federal law also establishes the transition dates and times at which daylight saving time occurs, if observed. It is ultimately the authority of the secretary of transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time. As of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC. Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich (GMT). Only the full-time zone names listed below are official; abbreviations are by common use conventions, and duplicated elsewhere in the world for different time zones. The United States and its surrounding areas use nine standard time zones. As defined by U.S. law they are:
Title: Time in Tennessee
Content:  Time in Tennessee, as in all U.S. states, is regulated by the United States Department of Transportation. About 73 percent of the counties in the state of Tennessee lie in the Central Time Zone, mostly the western and middle grand divisions, while East Tennessee is mostly in the Eastern Time Zone except for three counties in that division. All counties observe Daylight Saving Time.
Title: Time in Arizona
Content:  Time in Arizona, as in all U.S. states, is regulated by the United States Department of Transportation as well as by state and tribal law. All of Arizona is in the Mountain Time Zone. Since 1968, most of the state—with exceptions noted below—does not observe daylight saving time and remains on Mountain Standard Time (MST) all year. This results in most of Arizona having the same time as neighboring California each year from March to November, when locations in the Pacific Time Zone observe daylight saving time.

Title: Time in the United States
Content: Most use the standard time for their zone (or zones, where a state is divided between two zones), except for using daylight saving time during the summer months. Originally this ran from the last Sunday in April until the last Sunday in October. Two subsequent amendments, in 1986 and 2005, have shifted these days so that daylight saving time now runs from the second Sunday in March until the first Sunday in November.
