Some of zone records use 3 or 4 letter abbreviations that are tied to physical time zones, others use numeric UTC offsets. Time zone abbreviations for both Standard Time and Daylight Saving Time are shown exactly as they appear in the database. This table does not attempt to document any of the historical data which resides in the database. The UTC offsets are based on the current or upcoming database rules. Standard Time ( STD) and Daylight Saving Time ( DST) offsets from UTC in hours and minutes.įor zones in which Daylight Saving is not observed, the DST offset shown in this table is a simple duplication of the STD offset. Historical data for such zones is still preserved in the source code, but it is not included when compiling the database with standard options. The dagger symbol (†) signifies that the zone was canonical in a previous version of the database. Adding the country's 3 dependencies (see table below) brings the total to 9 time zones. Link - An alternative name (alias) which links to a canonical zone.

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.World map showing time zones from the tz database version 2017a 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). Primarily, UTC is based on mean solar time at the prime meridian running through Greenwich, UK. The offset is expressed as either UTC- or UTC+ and the number of hours and minutes. All time zones are defined by their offset from UTC. 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. What Is UTC UTC Coordinated Universal Timeis the 24-hour time standard used as a basis for civil time today. The name Coordinated Universal Time was officially adopted in 1967. In 1960, the International Radio Consultative Committee formalized the concept of UTC, and it was put into practice the year after. 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 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. Monterrey, Mexico time is 6 hours behind UTC. Simply mouse over the colored hour-tiles and glance at the hours selected by the column. Universal Time (UT) was created at the International Meridian Conference in 1884. This time zone converter lets you visually and very quickly convert UTC to Monterrey, Mexico time and vice-versa. It is used to compare the pace provided by TAI with the actual length of a day on Earth. 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.Two components are used to determine UTC: 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 The Greenwich Meridian in London, England. Business Date to Date (exclude holidays).
