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
= -0.2 seconds beginning 14 June 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 = .0517 + .0734 cos A + .0320 sin A + .0722 cos C - .1065 sin C
y = .3479 + .0284 cos A - .0700 sin A - .1065 cos C - .0722 sin C
UT1-UTC = -.1873 - .00094 (MJD - 54347) - (UT2-UT1)
where A = 2*pi*(MJD-54342)/365.25 and C = 2*pi*(MJD-54342)/435.
TAI-UTC(MJD 54343) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54342)**0.80 S t = 0.00025 (MJD-54342)**0.75
