atomic time

Without them, atomic time would move an extra second ahead of astronomical time once every 500 days.

During this time, irregularities in the atomic time were detected and corrected.

In the late 1940s the atomic clock was developed and several laboratories began atomic time scales.

Atomic time piece never needs winding or resetting once you set it to your time zone.

They're used whenever the disparity between atomic time and astronomical time reaches 0.9 of a second.

Time as measured by Earth's rotation has accumulated a delay with respect to atomic time standards.

This led to the internationally agreed definition of the latest SI second being based on atomic time.

This also means that ET is a uniform time scale, as is atomic time.

With the introduction of atomic clocks in the 1950s, it was found that ET could be better realized as atomic time.

The UTC timestamp in use worldwide is an atomic time standard.

The earth rotation is uneven, so UT is not linear with respect to atomic time.

(See the article on International Atomic Time for details.)

The International Atomic Time is calculated there.

To keep the atomic time standard that we now live by synchronized with earth time, a "leap second" will be added, Dr. Baker said.

Such wristwatches use the radio signal to adjust and maintain atomic time, even adjusting for daylight time, and the date.

The National Grid, mobile phone networks and satellite TV signals all rely on atomic time, as does your satnav.

Wandrey develops the sculpture Atomic-Time-Guardian (1988) as the guardian angel or protector of atomic time.

TDT is a uniform atomic time scale, whose unit is the SI second.

Some systems use GPS satellite receivers to obtain exact atomic time, for perfect synchronization with satellite-delivered programming.

Sanborn has written a book titled In Atomic Time: Pure Science and Sculpture.

The March 7 eclipse slowed a radio transmission of atomic time from North Carolina to Washington, D.C.

Iron is magnetic; once it is magnetized it stays magnetized for a long time compared to any atomic time.

International Atomic Time (French: Temps atomique international)

The ground floor of the two story building contained the air-conditioning, transmitter heat exchanger controls, equipment load center data input junction box and ex-Mercury atomic time standard.

Until a relatively few years ago, lengthy frequency chains were needed to connect the microwave frequency of a cesium or other atomic time source to optical frequencies.
