Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. The coordination of time and frequency transmissions around the world began on 1 January The system has been adjusted several times, including a brief period where the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time SAT " before a new UTC was adopted in and implemented in This change also adopted leap seconds to simplify future adjustments.
This CCIR Recommendation "stated that a carrier frequencies and time intervals should be maintained constant and should correspond to the definition of the SI second; b step adjustments, when necessary, should be exactly 1 s to maintain approximate agreement with Universal Time UT ; and c standard signals should contain information on the difference between UTC and UT.
A number of proposals have been made to replace UTC with a new system that would eliminate leap seconds. A decision whether to remove them altogether has been deferred until This abbreviation arose from a desire by the International Telecommunication Union and the International Astronomical Union to use the same abbreviation in all languages. Time zones around the world are expressed using positive or negative offsets from UTCas in the list of time zones by UTC offset.
For sub-microsecond precision, clients can obtain the time from satellite signals. UTC is also the time standard used in aviation e.Mass ban discord bot
Weather forecasts and maps all use UTC to avoid confusion about time zones and daylight saving time. Amateur radio operators often schedule their radio contacts in UTC, because transmissions on some frequencies can be picked up in many time zones.
UTC divides time into days, hours, minutes and seconds. Days are conventionally identified using the Gregorian calendarbut Julian day numbers can also be used. The number of seconds in a minute is usually 60, but with an occasional leap secondit may be 61 or 59 instead. The extra second is called a leap second. The irregular day lengths mean that fractional Julian days do not work properly with UTC.
SinceUTC is calculated by subtracting the accumulated leap seconds from International Atomic Time TAIwhich is a coordinate time scale tracking notional proper time on the rotating surface of the Earth the geoid. These discontinuities take the form of leap seconds implemented by a UTC day of irregular length.
Discontinuities in UTC have occurred only at the end of June or December, although there is provision for them to happen at the end of March and September as well as a second preference. Users who require an approximation in real time must obtain it from a time laboratory, which disseminates an approximation using techniques such as GPS or radio time signals.
Such approximations are designated UTC kwhere k is an abbreviation for the time laboratory. Because of time dilationa standard clock not on the geoid, or in rapid motion, will not maintain synchronicity with UTC. Therefore, telemetry from clocks with a known relation to the geoid is used to provide UTC when required, on locations such as those of spacecraft.
It is not possible to compute the exact time interval elapsed between two UTC timestamps without consulting a table that shows how many leap seconds occurred during that interval.
By extension, it is not possible to compute the precise duration of a time interval that ends in the future and may encompass an unknown number of leap seconds for example, the number of TAI seconds between "now" and Therefore, many scientific applications that require precise measurement of long multi-year intervals use TAI instead. TAI is also commonly used by systems that cannot handle leap seconds.
Time zones are usually defined as differing from UTC by an integer number of hours,  although the laws of each jurisdiction would have to be consulted if sub-second accuracy was required.

Several jurisdictions have established time zones that differ by an odd integer number of half-hours or quarter-hours from UT1 or UTC.
Time zones were identified by successive letters of the alphabet and the Greenwich time zone was marked by a Z as it was the point of origin. The letter also refers to the "zone description" of zero hours, which has been used since see time zone history. This is especially true in aviation, where "Zulu" is the universal standard. 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.In military shorthand, the letter Z follows a time expressed in Greenwich Time.
Greenwich Time, now called Universal Coordinated Time, is the time at longitude 0 degrees 0 minutes - the prime meridian or longitudinal line that separates East from West in the world geographical coordinate system.Lego wyplash ninjago skeleton minifigure 2506 2509
Traditionally, ship and airplane navigation is conducted using Zulu time. Zulu time is usually expressed in terms of a hour clock using the Gregorian calendar time divisions of hours and minutes. Please check the box if you want to proceed.

Please create a username to comment. The concept of Zulu time was NOT created by the military - per se'. The British originated it and called their little island the center of the universe for Earth's Time Zones; therefore they are ZULU and everyone else adjusts to that time beat from Greenwich England.

I last taught the 3rd mate of tug boat how to do it in - I quit sailing because as an Able Bodied Seaman I knew more than all the mates that I ever sailed with and lost confidence in their abilities.

Semper Fi! BTW - I had been ship's captain in another life. Being an actual "Sea Captain" doesn't always denote one's present rank, more their qualifications to take a ship someplace and bring it back.

The aviation convention is to append the characters Z to times written as UTC and L to times written as local time. In the phonetic alphabet, Z is pronounced Zulu.

Departure and arrival time s, air traffic control clearance s, the valid time of weather reports and forecasts, and other time-sensitive information in aviation is expressed in UTC.
It only takes a minute to sign up. Zulu means the letter Z in radio communication. The letter Z designates UTC time. There is actually a list of time zones for each letter of the alphabet except J :. Imagine this: the time now is We will takeoff at and fly west.
Afterwards, at aroundwe will be 15 nautical miles away from the airport We actually cross a time zone and the actual flight time is 90 minutes.
But we've taken off with 60 minutes less fuel than we need. What do we do? Zulu time, as others have pointed out, refers to UTC. We use this time in aviation and meteorology and surely others because it is easier and it is standard. It's the same time everywhere on earth. If you are flying along the border between Arizona and New Mexico in the summer and given a hold:. Cessna hold at FIX, right turns, 10 mile legs, expect further clearance attime now This is a needless check that is distracting and can cause confusion all due to using a local time.
It is a similar situation when checking pre-flight weather. Weather is reported in Z time and this makes it easy to calculate when you will get to your destination and what forecast is valid for that time. If it were in local time you'd have to know additional information about time zones, which again could be a source of error and is needless. Adding to potential confusion are regions of earth that keep odd adjustments.
For example, St.It is most commonly used in aviation and the military, as a way to sync up operations and reduce confusion when plannign of operations spanning multiple time zones. Each time zone has a letter and number designation. How are time zones named? They have many different names depending on who is using the time zone.
But first a little background on time zones.
There are 25 time zones in the world, each one separated by 15 degrees of longtitude. Each time zone encompasses a swatch of the globe extending from north to south between two longitude bars 15 degrees apart. Every time zone has a common name, letter, and number designation. The military uses letters to name time zones. This is the starting point for the universal time zone numbering system. If you are smart, you probably have figured out that one letter would have to be left off, since there are 26 letters in the alphabet.
You are correct. Zulu time is used as civilian time in several countries. Any country falling in this particular time zone, use it everyday. The civilians in these countries use the hour clock. So, they use Zulu time in hour format.
