Today, Greenwich Mean Time (GMT) is only the name of a time zone that is used by a few countries in Africa and Western Europe, including the UK during winter and all year in Iceland. Since then, GMT is no longer a time standard. Until 1972, Greenwich Mean Time (also known as Zulu time) was the same as Universal Time (UT). UTC was adjusted several times until 1972, when leap seconds were introduced to keep UTC in line with the Earth's rotation, which is not entirely even, and less exact than atomic clocks. The name Coordinated Universal Time was officially adopted in 1967. This page lists all countries of the world, plus major regions and cities, grouped by their current UTC offset. In 1960, the International Radio Consultative Committee formalized the concept of UTC, and it was put into practice the year after. Time zones List of countries grouped by current UTC offset. This may affect the behavior and the output of examples that illustrate the DateTime, DateTimeOffset, and TimeZoneInfo types and their members. The transit circle is a part of the telescope's mechanics and it is still cited as the prime meridian's original reference (0° longitude). The local time zone of the Try.NET inline code runner and playground is Coordinated Universal Time, or UTC. The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London. This is the basis for the 24-hour time zone system we know today.Īt the time, Greenwich Mean Time (GMT) was chosen as the world’s time standard. Universal Time (UT) was created at the International Meridian Conference in 1884. Note that United Kingdom is not on GMT during summer. Same time as for GMT (Greenwich Mean Time) and Zulu time. It is used to compare the pace provided by TAI with the actual length of a day on Earth. Glossary UTC Coordinated Universal Time - the international basis for other time zones. Universal Time (UT1): Also known as astronomical time or solar time, it refers to the Earth's rotation.International Atomic Time (TAI): A time scale that combines the output of some 400 highly precise atomic clocks worldwide, and provides the exact speed for our clocks to tick.They are, from west to east: Acre Time (ACT), Amazon Time (AMT), Braslia Time (BRT), and Fernando de Noronha Time (FNT). Two components are used to determine UTC: Sun & Moon Eclipses Multiple Time Zones Time Zones Currently Being Used in Brazil Four Brazil Time Zones There are four standard time zones in Brazil. The world's timing centers have agreed to keep their time scales closely synchronized - or coordinated - therefore the name Coordinated Universal Time. UTC is the time standard commonly used across the world. ©/stocknshares A Standard, Not a Time Zone Another UTC format is a 12-hour clock time (AM/PM) xx:xx:xx. The Greenwich Meridian in London, England. For instance, UTC time in ISO-8601 is xx:xx:xxZ. Business Date to Date (exclude holidays).Return "Registry data on the Central Standard Time zone has been corrupted. Return "The registry does not define the Central Standard Time zone." Monterrey, Mexico time is 6 hours behind UTC. Simply mouse over the colored hour-tiles and glance at the hours selected by the column. Var cstDateTime = TimeZoneInfo.ConvertTimeFromUtc(outputDateTime, cstZone) This time zone converter lets you visually and very quickly convert UTC to Monterrey, Mexico time and vice-versa. Var isWindows = RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ĬstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time") ĬstZone = TimeZoneInfo.FindSystemTimeZoneById("America/Chicago") If (DateTime.TryParse(dateTimeString, out DateTime outputDateTime)) If (string.IsNullOrWhiteSpace(dateTimeString)) Public static string ConvertUtcToCst(this string dateTimeString) Here's an example with the isWindows switch: public static class DateTimeHelper For example, "Central Standard Time" would be "America/Chicago". Here's another gotcha: If you're running your code on a Linux server, you need to use the Linux system for timezone names.
