	Local mean time - Wikipedia, the free encyclopedia
		Local mean time is a form of solar time that corrects the variations of local apparent time.
		Local mean time was used from the early nineteenth century, when local solar time or sundial time was last used, until standard time was adopted on various dates in the several countries.
		Standard time means that the same time is used throughout some region — usually, it was either offset from Greenwich Mean Time or was the local mean time of the capital of the region.

	Astronomical Leage - Astro Note 10: What Time Is It?
		Mean time uses the position of a fictitious "mean Sun" which moves smoothly and uniformly across the sky and is insensitive to the Earth's irregularities.
		Local mean time is determined by the mean Sun's position relative to the local meridian of the observer.
		Sidereal time is measured by the position of the vernal equinox relative to the meridian.

	Greenwich Mean Time - Wikipedia, the free encyclopedia
		Noon Greenwich Mean Time is not necessarily the moment when the Sun crosses the Greenwich meridian (and reaches its highest point in the sky in Greenwich) because of Earth's uneven speed in its elliptic orbit and its axial tilt.
		The fictitious mean sun is the annual average of this nonuniform motion of the true Sun, necessitating the inclusion of mean in Greenwich Mean Time.
		Ireland adopted Greenwich Mean Time in 1916, supplanting Dublin Mean Time.

		LMT (Local Mean Time) is mean solar time reckoned from mean noon on a local meridian time based on the motion of the Sun were it to move uniformly along the celestial equator at a constant rate of motion.
		GMT Greenwich Mean Time is mean solar time reckoned from mean noon on the meridian of Greenwich.
		The transition from Sun Time to Mean Time occurred in Geneva in 1780; England, 1792; Berlin, 1810; and Paris, 1816.

		In this case ``mean'' means the average obtained by considering the rotation of the earth in the absence of the annual variations caused by obliquity and eccentricity.
		The mean solar time of the Greenwich meridian.
		Although the term GMT was not explicitly used, the standard time for legal purposes in the United States specified by 15USC261 was clarified and reaffirmed to be based on the mean solar time of meridians spaced at 15-degree intervals west of Greenwich; i.e., GMT.

	Time Keeping in Astronomy
		The basis of astronomical time is the rotation of the Earth on its axis.
		Note that LMT is not, in general, the same as the the civil time (standard time) at a location since the civil time is the same for all locations in that zone and is the LMT for the zone's standard longitude.
		Sidereal time is time kept relative to the stars instead of relative to the sun.

	History & info - Standard time began with the railroads
		Standard time in the US Standard time in time zones was instituted in the U.S. and Canada by the railroads on November 18, 1883.
		Prior to that, time of day was a local matter, and most cities and towns used some form of local solar time, maintained by a well-known clock (on a church steeple, for example, or in a jeweler's window).
		Fleming advocated the adoption of a standard or mean time and hourly variations from that according to established time zones.

	THE ORDER OF TIME: SCIENCE
		he equation of time refers to the irregularity of the natural length of a day as measured on a sundial.
		This irregularity is caused by the non-circuolar orbit of the earth spinning around the sun and the tilt of its axis relative to the sun.
		Twelve o'clock on the tempometer means that the sun at that time passes the meridian, goes through the south, the longitude of the place of the user.

	British Summer Time: historical information
		Before the railways, local mean time was the time kept by clocks and used for general purposes in the UK, insofar as people kept time by clocks rather than by the sun.
		Having established a simple, uniform timescale of GMT (the time for Ireland was changed in 1916 to also be GMT), it might be expected that this would have sufficed to establish the legal definition of time until the development of atomic timescales in the 1950s.
		This provided for the time in the Bailiwick of Jersey to be one hour in advance of Greenwich mean time throughout the year (to be known as “Jersey Standard Time”) from 27 October 1968 until 31 October 1971, the time of day being unspecified in both cases.
