MJD = Julian Date - 2 400 000.5 days
UT2-UT1 = 0.022 sin(2*pi*T) - 0.012 cos(2*pi*T)
- 0.006 sin(4*pi*T) + 0.007 cos(4*pi*T)
where pi = 3.14159265... and T is the date in Besselian years.
TT = TAI + 32.184 seconds
DUT1= (UT1-UTC) transmitted with time signals
= -0.6 seconds beginning 17 March 2005 at 0000 UTC
Beginning 1 January 1999:
TAI-UTC(BIPM) = 32.000 000 seconds

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 = .0509 + .0939 cos A + .0072 sin A - .1047 cos C + .0784 sin C
y = .3467 + .0070 cos A - .0955 sin A + .0784 cos C + .1047 sin C
UT1-UTC = -.6350 - .00041 (MJD - 53626) - (UT2-UT1)
where A = 2*pi*(MJD-53621)/365.25 and C = 2*pi*(MJD-53621)/435.
TAI-UTC(MJD 53622) = 32.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-53621)**0.80 S t = 0.00025 (MJD-53621)**0.75

No leap second was introduced in UTC on 30 June 2005.
On 04 July 2005, the annoucement was made that a positive leap second
will be 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

Important Notice - IAU 2000 Resolution Compliancy Information
**************************************************************************
Resolutions passed at the 24th General Assembly of the International
Astronomical Union (IAU) recommend the implementation of a number of new
procedures concerning the transformation between the celestial and
terrestrial reference systems. Information regarding these procedures
is available in Chapter 5 of the IERS Conventions 2003 available at
.
With these resolutions, beginning on 1 January 2003, IERS Bulletins A and
B will publish new products in addition to those already published. These
products will include the celestial pole offsets X_obs-X_IAU2000A
and Y_obs-Y_IAU2000A where
X_obs and Y_obs are the observed X, Y coordinates of the Celestial
Intermediate Pole in the Geocentric Celestial Reference System, and
X_IAU2000A and Y_IAU2000A are the celestial pole coordinates provided by
using the IAU2000A Precession-Nutation theory.
It is expected that Celestial Pole offsets related to the IAU1980 Nutation
Theory will continue to be published through 30 September 2005. The new
celestial pole offsets related to the new IAU2000A Precession-Nutation
theory will be produced in a separate data file as well as appended to
to this file.
