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
= -0.5 seconds beginning 07 August 2008 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds

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 = .0671 + .0990 cos A - .0553 sin A + .0446 cos C - .1363 sin C
y = .3418 - .0409 cos A - .0930 sin A - .1363 cos C - .0446 sin C
UT1-UTC = -.5509 - .00088 (MJD - 54770) - (UT2-UT1)
where A = 2*pi*(MJD-54762)/365.25 and C = 2*pi*(MJD-54762)/435.
TAI-UTC(MJD 54763) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54762)**0.80 S t = 0.00025 (MJD-54762)**0.75
