The other has been in force since before history was recorded: astronomical time.

The astronomical time scale was far slower than the human.

Astronomical time scheduling requires that the location of the building be set.

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

By way of introduction, he remarked that there are men doing "absolutely astronomical time," then led the youths inside.

When computed, this astronomical time cycle would give the following results:

The astronomical time cycles contained in the text were remarkably accurate at the time.

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

Astronomical time schedules incorporate sunrise and sunset times, often used to switch outdoor lighting.

This took as much as thirty seconds-an astronomical time on the implant's scale.

The high population of the asteroid belt makes for a very active environment, where collisions between asteroids occur frequently (on astronomical time scales).

Baillaud's concern for the astronomical time standard led him to be an outspoken opponent of daylight saving time.

If the user needed to know time-of-day rather than elapsed time, clocks were synchronized with astronomical time.

The Gate Clock originally indicated astronomical time, in which the counting of the 24 hours of each day starts at noon.

The theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales.

Two large clocks on the basilica's facade indicate, on the left, the astronomical time and, on the right, the hours for the canonical prayers.

Unlike former astronomical time scales, TCG is defined in the context of the general theory of relativity.

Languet de Gergy initially wished to establish the exact astronomical time in order to ring the bells at the most appropriate time of day.

Its distance from the Earth, 65 million light-years, means that what astronomers are seeing took place 65 million years ago, a very brief period in astronomical time.

Astronomical time (sunrise/sunset)

It could hardly be very durable, on the scale of astronomical time, but then no solar system within the Milkpail was long-lived in terms of stellar chronology.

Calibration of the caesium standard atomic clock was carried out by the use of the astronomical time scale ephemeris time (ET).

If Bolt posted astronomical times in the last olympics and thousands of people including myself are accusing him of using performance enhancements, then what does that say about you?

The end points of the lines in Altona and Kiel were found have a time difference in exact astronomical time of about 40 seconds due to their location.

Seconds 01-16 carry information for the current minute about the difference (DUT1) between atomic and astronomical time, and the remaining seconds convey the time and date code.
