These days, a leap second is inserted in UTC to keep it within 0.9 second of UT1
In order for our civil time (UTC based on TAI) to keep "in step" with the changing earth rotational speed, UT1
leap seconds are added to the year from time to time to compensate for this slowing down.
defines a second as one-86,400th of one rotation of the Earth, and because the Earth's spin is slowing, UTC and GMT are slipping out of sync; albeit very slowly.
DISTINGUISHED WAKE: Robot UT1
, with head of sales Mick Jones, is made by SMD, which is moving to the site where Turbinia, right, was created.
Figure 3a and b show the paths of ultrasonic observed at the UT locations with COIM using an ultrasonic pulse-echo technique, where only first core arrives at the UT1
located near the end of the mold cavity in Fig.
Her bravery came as the UT1
station hailed Viktor Yanukovych's triumph over opposition leader Viktor Yushchenko.

Travis Freed, CAPT Bob Snyder, LT Lebron Butts, BUCS Tom Marsh, and CE1 Mike Fields.
Strictly speaking, the rotation is not uniform, and it is measured either by means of Universal Time UT1
, or its time derivative, length-of-day (LOD).
Unit Telescope 1 (UT1
) is the first operating 8-meter reflector among the four that will soon constitute the Very Large Telescope, which the European Southern Observatory (ESO) is building in northern Chile, a second, UT2, is now in service too.
