atomic time การใช้

• TT indirectly underlies UTC, via International Atomic Time ( TAI ).
• The Earth's slowing has created gaps between astronomical and atomic time.
• This also means that ET is a uniform time scale, as is atomic time.
• That is why the master clocks of the electricity companies show mean time, not atomic time.
• In the late 1940s the atomic clock was developed and several laboratories began atomic time scales.
• These clocks collectively define a continuous and stable time scale, International Atomic Time ( TAI ).
• International Atomic Time ( TAI ) was set equal to UT2 at 1 January 1958 0 : 00 : 00.
• Such wristwatches use the radio signal to adjust and maintain atomic time, even adjusting for daylight time, and the date.
• Practical examples include the International Atomic Time standard and its relationship with the Barycentric Coordinate Time standard used for interplanetary objects.
• The live connection will allow the watches to be kept at exact atomic time, and automatically update to new time zones.
• One is called International Atomic Time, or TAI, which is computed by the International Bureau of Weights and Measures in Paris.
• This is kept in sync with the official civilian time reference maintained by NIST and contributes to the International Atomic Time.
• The live connection will allow the watches to be kept at exact atomic time, and automatically update when crossing time zones.
• With the introduction of atomic clocks in the 1950s, it was found that ET could be better realized as atomic time.
• The difference between Terrestrial Time ( TT ) ( the successor to ephemeris time ) and atomic time was later defined as follows:
• Your argument is based on the sole premise that modern clocks are manufactured to keep atomic time as opposed to mean solar time.
• "The ( Chernobyl ) atomic time bomb is still ticking . . . its problems are complex and require coordinated assistance, " the statement said.
• Since then, friction from winds and tides has slowed the Earth's rotation, and the planet simply has not been able to keep up with atomic time.
• ET was given a new name, Terrestrial Time ( TT ), and for most purposes ET = TT = International Atomic Time + 32.184 SI seconds.
• But a new technical wrinkle in atomic timing is incorporated in the latest descendant of Rabi's atomic clock idea _ a laser system for cooling cesium atoms.
