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 28 September 2006 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds

* As of Bulletin A Vol. XX, No. 1, on 4 January 2007, we have *
* adopted the new IVS combined series ivs07r1e.eops. The net *
* effect appears to be less than 0.1 mas in polar motion and *
* 10 us in UT1-UTC. *

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 = .0654 - .0367 cos A - .0878 sin A - .0828 cos C + .0918 sin C
y = .3367 - .0754 cos A + .0320 sin A + .0918 cos C + .0828 sin C
UT1-UTC = .0181 - .00089 (MJD - 54109) - (UT2-UT1)
where A = 2*pi*(MJD-54104)/365.25 and C = 2*pi*(MJD-54104)/435.
TAI-UTC(MJD 54105) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54104)**0.80 S t = 0.00025 (MJD-54104)**0.75
