PREDICTIONS:
The following formulas will not reproduce the predictions given below,
but may be used to extend the predictions beyond the end of this table.
x = .0731 + .0064 cos A - .1183 sin A - .1215 cos C + .0720 sin C
y = .3423 - .1005 cos A - .0048 sin A + .0720 cos C + .1215 sin C
UT1-UTC = .0420 - .00085 (MJD - 54081) - (UT2-UT1)
where A = 2*pi*(MJD-54076)/365.25 and C = 2*pi*(MJD-54076)/435.
TAI-UTC(MJD 54077) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54076)**0.80 S t = 0.00025 (MJD-54076)**0.75

A positive leap second was introduced in UTC on 31 December 2005.
The sequence of dates of the UTC second markers will be:
2005 December 31, 23h 59m 59s
2005 December 31, 23h 59m 60s
2006 January 1, 0h 0m 0s
The difference between UTC and the International Atomic Time (TAI) is:
from 1999 January 1, 0h UTC, to 2006 January 1 0h UTC : UTC-TAI = - 32s
from 2006 January 1, 0h UTC, until further notice : UTC-TAI = - 33s
