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
= -0.3 seconds beginning 29 November 2007 at 0000 UTC
= -0.4 seconds beginning 13 March 2008 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds
**********************************************************************
* As of Bulletin A Vol. XXI, No. 009, on 28 February 2008, we have *
* incorporated the new USNO VLBI solutions usno2008a and int2008a. *
* The effect appears to be less than 0.10 mas in polar motion and *
* 10 us in UT1-UTC. *

The contributed observations used in the preparation of this Bulletin
are available at . The
contributed analysis results are based on data from Very Long Baseline
Interferometry (VLBI), Satellite Laser Ranging (SLR), the Global
Positioning System (GPS) satellites, Lunar Laser Ranging (LLR), and
meteorological predictions of variations in Atmospheric Angular
Momentum (AAM).

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 = .0532 - .0975 cos A - .0148 sin A - .0859 cos C + .0696 sin C
y = .3551 - .0170 cos A + .0901 sin A + .0696 cos C + .0859 sin C
UT1-UTC = -.3244 - .00084 (MJD - 54532) - (UT2-UT1)
where A = 2*pi*(MJD-54524)/365.25 and C = 2*pi*(MJD-54524)/435.
TAI-UTC(MJD 54525) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54524)**0.80 S t = 0.00025 (MJD-54524)**0.75
