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
= +0.0 seconds beginning 22 December 2006 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds
**********************************************************************
* As of Bulletin A Vol. XX, No. 003, on 18 January 2007, we have *
* incorporated the new GSFC VLBI solutions gsf2007a and gsfint19. *
* We have also incorporated the ILRS A series. We have taken *
* this opportunity to readjust the VLBI systematic errors to *
* bring them into closer alignment with the IERS C04 system and *
* to implement more realistic errors for the most recent EOP *
* estimates. *
* *
* The effect appears to be less than 0.15 mas in polar motion and *
* 10 us in UT1-UTC. *

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 = .0570 - .0523 cos A - .0678 sin A - .0627 cos C + .0974 sin C
y = .3396 - .0591 cos A + .0448 sin A + .0974 cos C + .0627 sin C
UT1-UTC = -.0004 - .00091 (MJD - 54123) - (UT2-UT1)
where A = 2*pi*(MJD-54118)/365.25 and C = 2*pi*(MJD-54118)/435.
TAI-UTC(MJD 54119) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54118)**0.80 S t = 0.00025 (MJD-54118)**0.75
