PTP

The Precision Time Protocol (PTP) is a protocol to synchronize clocks in an IPv4 or IPv6 network. IEEE 1588 is designed for local networks, that require accuracies better than provided through NTP.

UT2

is UT1 corrected empirically for annual and semiannual variations of the rotation rate of the earth. The maximum correction is about 30 ms.

Category:deutsch

UT1

is UT0 corrected for variations in the polar motion and is proportional to the rotation of the earth in space. In its monthly bulletin, Circular-D, the Bureau International de l'Heure (BIH) publishes the current values of UT1 with respect to Internationa ...

UT0

measures UT with respect to the observer's meridian (position on earth) which varies because of the conical motion of the poles.

Category:deutsch

is the mean solar time of the prime meridian plus 12h, determined by measuring the angular position of the earth about its axis. The UT is sometimes designated GMT, but this designation should be avoided. The official U.S. Naval Observatory designation ...

Category:deutsch

is a reference system for specifying occurrences with respect to time.

Category:deutsch

is based on the rotation of the earth about the sun.

Category:deutsch

is determined and defined by observations of the earth with respect to the stars. A mean sidereal day is approxi-mately 23h 56m 4.09s. A solar year contains 366.24 sidereal days.

represents a binary count of elapsed time in seconds since the 1 January 1958 epoch. The Bureau International de l'Heure (BIH), the U.S. Naval Observatory (USNO), and other national observatories and laboratories maintain this count which accumulates a ...

Category:deutsch

is atomic time scale based on data from a worldwide set of clocks and is the internationally agreed to time reference. The TAI is maintained by the BIH, Paris, France. Its epoch was set such that TAI was in approximate agreement with UT1 on 1 January 19 ...

signifies the beginning of an event.

Category:deutsch

is obtained from observations of the motion of the moon about the earth.

Category:deutsch

is the predicted difference between UT1 and UTC and is given by DUT1 = UT1-UTC.

Category:deutsch

is maintained by the Bureau International de l'Heure (BIH) which forms the basis of a coordinated dissemination of standard frequencies and time signals. A UTC clock has the same rate as a TAI clock, but differs by an integral number of seconds. The st ...
