Several countries define their local time by reference to Greenwich Mean Time. [19] [20] Some examples are: Belgium: Decrees of 1946 and 1947 set legal time as one hour ahead of GMT. [19] Ireland: "Standard Time" (Irish: Am Caighdeánach) is defined as being one hour in advance of GMT. [21] "Winter Time" (Am Geimhridh) is defined as being the ...
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 ...
The International Space Station normally uses Greenwich Mean Time (GMT). [65] [66] Timekeeping on Mars can be more complex, since the planet has a solar day of approximately 24 hours and 40 minutes, known as a sol. Earth controllers for some Mars missions have synchronized their sleep/wake cycles with the Martian day, when specifically solar ...
UTC+5:30 is an identifier for a time offset from UTC of +05:30. This time is used in India [1] and Sri Lanka, [2] and was formerly used in Nepal, Pakistan and Bangladesh. [3] It is five and a half hours ahead of Coordinated Universal Time. Around 1.4 billion people live inside this time zone, making it the second-most populous after UTC+08:00. [4]
The ACP 121 standard actually refers to Greenwich Mean Time (GMT) as the base time standard, [1] but UTC has superseded GMT as a more precise time standard, [5] so the time offsets are commonly understood as UTC.
The main purpose of this page is to list the current standard time offsets of different countries, territories and regions. Information on daylight saving time or historical changes in offsets can be found in the individual offset articles (e.g. UTC+01:00) or the country-specific time articles (e.g. Time in Russia).
[2] [3] This was changed later in 1880, when Greenwich Mean Time was legally adopted throughout the island of Great Britain under the Statutes (Definition of Time) Act 1880 (43 & 44 Vict. c. 9). GMT was adopted on the Isle of Man on 30 March 1883, [4] Jersey in 1898, and Guernsey in 1913. Ireland adopted GMT in 1916, supplanting Dublin Mean ...
The broadcast pips replaced an electrical time coordination system based on the railway telegraph network, which itself was an extension of the mechanical time balls in Portsmouth (1829) and later Greenwich (1833), which enabled navigators aboard ships moored in those places to set their chronometers for the determination of longitude on voyages.
