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
= -0.4 seconds beginning 13 March 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 = .0703 + .0974 cos A + .0713 sin A + .0920 cos C + .0126 sin C
y = .3542 + .0743 cos A - .0835 sin A + .0126 cos C - .0920 sin C
UT1-UTC = -.4710 - .00081 (MJD - 54679) - (UT2-UT1)
where A = 2*pi*(MJD-54671)/365.25 and C = 2*pi*(MJD-54671)/435.
TAI-UTC(MJD 54672) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54671)**0.80 S t = 0.00025 (MJD-54671)**0.75
