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
= -0.1 seconds beginning 15 March 2007 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds

* As of Bulletin A Vol. XX, No. 013, on 29 March 2007, we have *
* incorporated the new GSFC VLBI solutions gsf2007b and gsfint20. *
* The effect appears to be less than 0.10 mas in polar motion and *
* 10 us in UT1-UTC. *

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 = .0525 - .0873 cos A + .0193 sin A + .0529 cos C + .1119 sin C
y = .3444 + .0183 cos A + .0776 sin A + .1119 cos C - .0529 sin C
UT1-UTC = -.0420 - .00096 (MJD - 54193) - (UT2-UT1)
where A = 2*pi*(MJD-54188)/365.25 and C = 2*pi*(MJD-54188)/435.
TAI-UTC(MJD 54189) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54188)**0.80 S t = 0.00025 (MJD-54188)**0.75
