While a mean time was proposed as early as 1835, the first law relating to a standardised time zone was the Telegraph Act of 1852, which stipulated that the national telegraph service adjust the clocks in its offices to "the central time of Amsterdam", which would later become known as "Amsterdam Time" (Dutch: Amsterdamse Tijd ) the mean time ...
UTC−05:00 – Eastern Time zone: roughly a triangle covering all the states from the Great Lakes down to Florida and east to the Atlantic coast UTC−04:00 – Puerto Rico, the U.S. Virgin Islands UTC+10:00 – Guam and the Northern Mariana Islands UTC+12:00 (WAKT) – Wake Island: Time in the United States: Antarctica: 10
This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00). It includes countries and regions that observe them during standard time or year-round.
The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software. [1] This is a list of time zones from release 2025a of the tz database. [2]
Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...
time in California = 09:30 − (−05:00) + (−08:00) = 06:30; time in India = 09:30 − (−05:00) + (+05:30) = 20:00. These calculations become more complicated near the time switch to or from daylight saving time, as the UTC offset for the area becomes a function of UTC time. The time differences may also result in different dates.
In 1981, Malaysia decided to standardise the time across its territories to a uniform UTC+08:00. Singapore elected to follow suit, citing business and travel schedules. [14] [15] The change took effect on New Year's Day (1 January) 1982 when Singapore moved half an hour forward on New Year's Eve (31 December) 1981 at 11:30 pm creating "Singapore Standard Time" (SST) or "Singapore Time" (SGT).
