		The standard unit for time is the SI second, from which larger units are defined like the minute, hour, day, week, month, year, decade, and century.
		In physics, time is defined as the distance between events along the fourth axis of the spacetime manifold.
		Special relativity showed that time cannot be understood except as part of spacetime, a combination of space and time.

	Time transfer - Wikipedia, the free encyclopedia
		Time transfer describes methods for transferring reference clock synchronization from one point to another, often over long distances.
		In some cases, multiple measurements are made over a period of time, and exact time synchronization only determined retrospectively.
		In particular time synchronization has been accomplished by using pairs of radio telescopes to listen to a pulsar, with the time transfer accomplished by comparing time offsets of the received pulsar signal.

		Time Transfer using Laser light (T2L2), is in the early stages of development.
		Due to the effects of SA, the direct time transfer accuracy of the GPS available to the civilian user is typically ±100 nanoseconds, and the corresponding instantaneous positioning uncertainty is ±100 m.
		The future of geodetic GPS time transfer is encouraging, and is intended to be used for regular time and frequency transfers between primary timing laboratories.

	USNO GPS Time Transfer
		GPS time is not adjusted and therefore is offset from UTC by an integer number of seconds, due to the insertion of leap seconds.
		As of January 1, 1999, GPS time is ahead of UTC by thirteen (13) seconds.
		The SPS time differences published by the USNO for the GPS represent the difference between the USNO MC and the GPS CC as recovered from individual satellites and permit a user to increase the precision of timing obtained by monitoring any of these satellites.

		Wallclock time (absolute time) is represented using the timestamp format of the Network Time Protocol (NTP), which is in seconds relative to 0h UTC on 1 January 1900 [5].
		As shown in the equation below, this is equivalent to the difference in the "relative transit time" for the two packets; the relative transit time is the difference between a packet's RTP timestamp and the receiver's clock at the time of arrival, measured in the same units.
		Since the interarrival jitter field is only a snapshot of the jitter at the time of a report, it may be necessary to analyze a number of reports from one receiver over time or from multiple receivers, e.g., within a single network.

	metas: Time and Frequency - Geodetic Time Transfer
		The geodetic time (or frequency) transfer (GeTT) uses geodetic GPS receivers and interferometric data-processing on the basis of all five GPS observables (Code CA, Code P1, Code P2, Phase L1, Phase L2).
		Transfer occurs between two GeTT stations, each of whose GPS receivers are controlled by the respective clock being compared.
		The data of the two terminals are electronically transferred to and recorded in a data-processing centre, and, 5 days after the observations are made, the results are released, in which the effects of satellite orbits, Earth rotation parameters, and the troposphere, to mention just the most important, can be taken into account.

		Students transferring from a private to a public institution or a public to a private institution are likely to transfer in the first two years of school.
		This chart shows the percentage of transfers that were upward transfers (from a 2-year to a 4-year institution); the percentage of lateral transfers (from a 2-year to a 2-year institution, or a 4-year to a 4-year institution); and the percentage of downward transfers (from a 4-year to a 2-year institution).
		Downward transfers and lateral transfers were more likely to happen by the end of the first year of school, while upward transfers were more evenly spread over the first three years of school.

		The arrival time will be calculated, in terms of the earth-based time scale, from knowledge of the times of pulse transmission and of reception at the earth station.
		Timing data from the GPS receiver will also serve to identify the times (epochs) of the specific light pulse transmitted from the earth stations.
		The discharge time is measured in terms of 10 ns clock periods, with the ratio of discharge-to-charge currents providing a 1000-to-1 "expansion" of time, thus yielding the 10 ps measurement resolution.

	New IGS Clock Products: A Global Time Transfer Assessment - GPS World
		Point-to-point timing comparisons can be further improved to the few-nanosecond range, even for single-frequency users over intercontinental distances, by coordinating observing schedules, exchanging data sets, and forming single-differences to remove the common-mode satellite errors.
		Geodetic analyses of GPS pseudorange and phase data determine the effective receiver "clock", which is at the ionosphere-free phase center of the antenna but offset by the electrical delay to the point in the receiver tracking loop where the observables are measured and time-tagged.
		For frequency transfers (as distinct from time transfers), the instrumental requirements are less stringent in an absolute sense but demand that the GPS hardware be highly insensitive to, or well isolated from, environmental change.

	The Hydrogen Maser Clock Project: A 10 ps Event Timer for Precise Time Transfer in Space (Site not responding. Last check: 2007-10-08)
		In this system, time kept by a clock located at an earth-based laser ranging station (LRS) is compared with the space clock's time by measuring the arrival time of a laser pulse at the spacecraft in terms of both the space and earth time scales.
		The main components of the HMC time transfer system are the retroreflector array; an omnidirectional fiberoptic light collector; a photomultiplier tube and preamplifier; and the event timer, consisting of a constant-fraction discriminator and a time interpolation circuit (TIM) with a resolution of 10 ps.
		The time transfer system's ability to resolve sub-nanosecond intervals results from a high-precision space-qualified event timer developed at the Los Alamos National Laboratory that is capable of timing with a resolution of 10 ps.

	Introduction to LabVIEW Control Design Toolkit by Finn Haugen, TechTeach
		Note: For continuous-time models, the CD Feedback function ignores a time delay included in any of the transfer functions in the feedback loop, that is, the resulting transfer function is derived assuming the time delays are zero.
		It is necessary to convert the time delay part of a discrete-time model to poles at the origin using the CD Convert Delay to Poles at Origin function for the CD Feedback function to produce the correct transfer function of the combined feedback loop.
		This also applies to discrete-time transfer functions which have been derived by discretizing an original continuous-time transfer function, that is, you have to use the CD Convert Delay to Poles at Origin function for the CD Feedback function to produce the correct result.
