Some few lines set unto a solemn time. --Beau. & Fl. Note: Time is often used in the formation of compounds, mostly self-explaining; as, time-battered, time-beguiling, time-consecrated, time-consuming, time-enduring, time-killing, time-sanctioned, time-scorner, time-wasting, time-worn, etc. Absolute time, time irrespective of local standards or epochs; as, all spectators see a lunar eclipse at the same instant of absolute time. Apparent time, the time of day reckoned by the sun, or so that 12 o'clock at the place is the instant of the transit of the sun's center over the meridian. Astronomical time, mean solar time reckoned by counting the hours continuously up to twenty-four from one noon to the next. At times, at distinct intervals of duration; now and then; as, at times he reads, at other times he rides. Civil time, time as reckoned for the purposes of common life in distinct periods, as years, months, days, hours, etc., the latter, among most modern nations, being divided into two series of twelve each, and reckoned, the first series from midnight to noon, the second, from noon to midnight. Common time (Mil.), the ordinary time of marching, in which ninety steps, each twenty-eight inches in length, are taken in one minute. Equation of time. See under Equation, n. In time.

    1. In good season; sufficiently early; as, he arrived in time to see the exhibition.

    2. After a considerable space of duration; eventually; finally; as, you will in time recover your health and strength. Mean time. See under 4th Mean. Quick time (Mil.), time of marching, in which one hundred and twenty steps, each thirty inches in length, are taken in one minute. Sidereal time. See under Sidereal. Standard time, the civil time that has been established by law or by general usage over a region or country. In England the standard time is Greenwich mean solar time. In the United States and Canada four kinds of standard time have been adopted by the railroads and accepted by the people, viz., Eastern, Central, Mountain, and Pacific time, corresponding severally to the mean local times of the 75th, 90th, 105th, and 120th meridians west from Greenwich, and being therefore five, six, seven, and eight hours slower than Greenwich time. Time ball, a ball arranged to drop from the summit of a pole, to indicate true midday time, as at Greenwich Observatory, England. --Nichol. Time bargain (Com.), a contract made for the sale or purchase of merchandise, or of stock in the public funds, at a certain time in the future. Time bill. Same as Time-table. [Eng.] Time book, a book in which is kept a record of the time persons have worked. Time detector, a timepiece provided with a device for registering and indicating the exact time when a watchman visits certain stations in his beat. Time enough, in season; early enough. ``Stanly at Bosworth field, . . . came time enough to save his life.'' --Bacon. Time fuse, a fuse, as for an explosive projectile, which can be so arranged as to ignite the charge at a certain definite interval after being itself ignited. Time immemorial, or Time out of mind. (Eng. Law) See under Immemorial. Time lock, a lock having clockwork attached, which, when wound up, prevents the bolt from being withdrawn when locked, until a certain interval of time has elapsed. Time of day, salutation appropriate to the times of the day, as ``good morning,'' ``good evening,'' and the like; greeting. To kill time. See under Kill, v. t. To make time.

       1. To gain time.

       2. To occupy or use (a certain) time in doing something; as, the trotting horse made fast time. To move against time, To run against time, or To go against time, to move, run, or go a given distance without a competitor, in the quickest possible time; or, to accomplish the greatest distance which can be passed over in a given time; as, the horse is to run against time. True time.

          1. Mean time as kept by a clock going uniformly.

          2. (Astron.) Apparent time as reckoned from the transit of the sun's center over the meridian.

n. Time as measured by synchronize clocks in different geographical locations within a time zone to the same time, rather than using the local meridian, as in local mean time or solar time.

n. the official time in a local region (adjusted for location around the Earth); established by law or custom [syn: civil time, local time]

Many longitudes or meridian pass through the countries and each has its own local time. To avoid the confusion the local time of central meridian passing through that country is taken as the time for that entire country , which is known as the standard time.

Standard time is the synchronization of clocks within a geographical area or region to a single time standard, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard. Historically, the concept was established during the 19th century to aid weather forecasting and train travel. Applied globally in the 20th century, the geographical areas became extended around evenly spaced meridians into time zones which (usually) centered on them. The standard time set in each time zone has come to be defined in terms of offsets from Universal Time. In regions where daylight saving time is used, that time is defined by another offset, from the standard time in its applicable time zone(s).

The adoption of standard time, because of the inseparable correspondence between time and longitude, solidified the concepts of halving the globe into an eastern and western hemisphere, with one prime meridian (as well its opposite International Date Line) replacing the various prime meridians that had previously been used.

In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may occur but have not been observed.

Standard Time is the debut album by former Wings guitarist Laurence Juber, released in 1982 on vinyl and never re-released. Some of the songs were recorded when Juber was still a member of Wings. Fellow Wings members Paul McCartney, Denny Laine and Steve Holley also performed on the album.
