The difference between your time zone and the time in your city is the number of lessons. GPS, Global Positioning System time, is the nuclear time line used by the nuclear timers in the GPS earth observation units and the GPS-satellite. Loran-C, Long Range Navigation Time, is an nuclear time line developed by nuclear timers in Loran-C-track transmitters.
TAI, Temps Atomique Internacional, is the global nuclear time base model that uses a continual SI second count. Greenwich meridian in the space age, nuclear time, longitude, etc.
Timing systems and data - GPS time
From time to time it is necessary to use the detail as GPS time stamps are labeled. This GPS information allows a recipient to change the GPS time to Universal Time (really UTC or Universal Time Coordinated) or any time area. The universal time was formerly known as Greenwich Mean Time or Zulu Time.
The GPS time is a uniform time line from 1.5.1980 to 1.6.1980 at noon. The 6th of January 1980 is a Sunday. The GPS time is counted in seconds and seconds of a fortnight. Weekdays are marked with numbers, Sunday is 0, 1 Monday, etc. The GPS-Wek 0 started at the beginning of the GPS time series.
The time within each fortnight is usually referred to as the second of the second. In some cases, the second weeks (SOW) are divided into a weekday (DOW) between 0 and 6 and a second weeks (SOD) between 0 and 86400. After 1860 the information is considered trustworthy and after 1956 very good nuclear time information was used.
The work of Morrison of the Royal Greenwich Observatory is the basis for this. Each year, the "world as a clock" is about one second away from nuclear time. From 1972, the global time measurement fellowship declared itself ready to add or take out 1 second of time to the subTC time base to align the Earth's orbit within one second of it.
It is either 1 January or 1 July of each year. It' like the inclusion of February 29th in intercalary years. For this reason, these were referred to as leap seconds. You can find a comprehensive description of the switching seconds on the website of the US Naval Observatory WWW. Skips in the chart are caused by switching seconds of the util.
Since GPS time has no leap seconds, it changes by 1 second with reference to HTC when a leap second is added. Both timescales were adjusted with the start of GPS time on January 6, 1980. On the next leap second, on July 1, 1981, the timer began to report a number 1 second less than GPS time.
Until 2000 there were 13 switching seconds. GPS satellite navigational messages contain the number of seconds between GPS and underTC time. There is also an indication when the next leap second will be added, if known. As a rule, the decision to insert a leap second is only made approx. 2month before.
It means a specific time period for an astrologer, known as UT1, which is defined by the actual rotation of the world. It is also used in many non-scientific books as Greenwich Mean Time (GMT). Universal Time Coordinated (UTC). This is what you are hearing from the time wards WWV, CHU etc.
This is a time framework built on the basis of atoms and oriented towards the zero length time area. It is what we use in our daily lives: ultraTC, plus an offsets for time bands. An astronomer uses a time line that is uniform in the number of dates they call the Julian date. The origins of this date system date far back in time, on 0 January 4173 B.C. at midday.
It is a graduated measure of the number of active ingredients in a given time. On January 1, 2000 at midday JD = 2,451,545. In the past the dates were begun at midday, hence the use of midday as a base time. There' s a slightly altered JD dial, which is common in today's scholars.
Introducing thiscale was used to indicate the transitions of the night at half past eight, in accordance with the civil time. So, January 1, 2000 will be MJD of 51,544 at midday.
