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 15 March 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). *

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 = .0552 - .0726 cos A + .0582 sin A + .1071 cos C + .0838 sin C
y = .3466 + .0547 cos A + .0651 sin A + .0838 cos C - .1071 sin C
UT1-UTC = -.0723 - .00097 (MJD - 54228) - (UT2-UT1)
where A = 2*pi*(MJD-54223)/365.25 and C = 2*pi*(MJD-54223)/435.
TAI-UTC(MJD 54224) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54223)**0.80 S t = 0.00025 (MJD-54223)**0.75
