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

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 = .0588 - .0851 cos A + .0348 sin A + .0768 cos C + .1054 sin C
y = .3465 + .0329 cos A + .0765 sin A + .1054 cos C - .0768 sin C
UT1-UTC = -.0574 - .00097 (MJD - 54207) - (UT2-UT1)
where A = 2*pi*(MJD-54202)/365.25 and C = 2*pi*(MJD-54202)/435.
TAI-UTC(MJD 54203) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54202)**0.80 S t = 0.00025 (MJD-54202)**0.75
