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
**********************************************************************
* As of Bulletin A Vol. XX, No. 023, on 07 June 2007, we will *
* adopt the new 05C04 EOP system. This will result in a jump of *
* less than 0.5 mas in polar motion and 10 us in UT1-UTC. The *
* only users who need to be concerned with this change are those *
* who need EOP accuracy to better than 1.0 mas (~3 cm at the *
* Earth's surface, ~13 cm at GPS orbit). *

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 = .0569 - .0477 cos A + .0774 sin A + .1255 cos C + .0503 sin C
y = .3458 + .0716 cos A + .0412 sin A + .0503 cos C - .1255 sin C
UT1-UTC = -.1020 - .00097 (MJD - 54249) - (UT2-UT1)
where A = 2*pi*(MJD-54244)/365.25 and C = 2*pi*(MJD-54244)/435.
TAI-UTC(MJD 54245) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54244)**0.80 S t = 0.00025 (MJD-54244)**0.75
