What time is utc time

Coordinated Universal Time or UTC is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones.

Here, you can learn what time is it in UTC time now and what the most accurate time now is , use our UTC time zone converter designed to easily convert time from current time in UTC to one of over a hundred presently existing time zones, as well as use some useful links at the bottom of the page collected for you by the experts of our team. Since the s, this time standard has been globally used as the most precise time standard, instead of formerly used GMT standard, which has turned now into a regular time zone. In order to learn the current time in UTC , it is enough for you just to open the main page of our website. In addition, you can also see a few types of UTC time format, with some being very widespread, and some being less commonly used. Those who plan a trip or an online meeting with their overseas business partners, those who have friends on the other continents and want to make a call at a convenient time can use this fast and effective UTC time zone converter.

Naval Observatory. At the end of the 21st century, LOD will be roughly 86,

By Anne Buckle and Vigdis Hocken. In November , the General Conference on Weights and Measures CGPM —an international body that decides on global standards for how things are measured—passed a resolution asking the International Telecommunication Union ITU to consider changing the way we define civil time. Read the full story. UTC is the time standard commonly used across the world. The world's timing centers have agreed to keep their time scales closely synchronized - or coordinated - therefore the name Coordinated Universal Time. This is the basis for the hour time zone system we know today. The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London. The name Coordinated Universal Time was officially adopted in UTC was adjusted several times until , 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. Since then, GMT is no longer a time standard.

Naval Observatory started to develop atomic frequency time scales; by , these time scales were used in generating the WWV time signals, named for the shortwave radio station that broadcasts them. Oxford Dictionaries: British and World English. The jumps increased in size to 0. London: Philip Wilson. International Telecommunication Union. The irregular day lengths mean fractional Julian days do not work properly with UTC. In Babcock, A. Amateur radio operators often schedule their radio contacts in UTC, because transmissions on some frequencies can be picked up in many time zones. UTC does not change with a change of seasons, but local time or civil time may change if a time zone jurisdiction observes daylight saving time summer time. International Astronomical Union Symposia. Since then, leap seconds have occurred on average about once every 19 months, always on 30 June or 31 December. These discontinuities take the form of leap seconds implemented by a UTC day of irregular length. Greenwich Time and the Longitude.

No matter how strongly you might feel about it, daylight saving time will once again move clocks an hour forward soon. Here's what to know about the changing of the clocks this spring, and how the practice came about. Daylight saving time is the practice of setting the clock forward one hour in the spring to have the sunrise and sunset at a more reasonable hour.

Seaman, Rob Time zones are usually defined as differing from UTC by an integer number of hours, [19] although the laws of each jurisdiction would have to be consulted if sub-second accuracy was required. USA Today. Archived from the original on 23 September Physical Review Letters. Therefore, many scientific applications that require precise measurement of long multi-year intervals use TAI instead. In , the U. Retrieved 4 January In a controversial decision, the frequency of the signals was initially set to match the rate of UT, but then kept at the same frequency by the use of atomic clocks and deliberately allowed to drift away from UT. In a resolution was adopted by the General Conference on Weights and Measures to redefine UTC and abolish leap seconds, but keep the civil second constant and equal to the SI second, so that sundials would slowly get further and further out of sync with civil time. It will take about 50, years for a mean solar day to lengthen by one second at a rate of 2 ms per century.
