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

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 = .0590 - .0810 cos A - .0070 sin A + .0065 cos C + .1073 sin C
y = .3441 - .0065 cos A + .0706 sin A + .1073 cos C - .0065 sin C
UT1-UTC = -.0329 - .00095 (MJD - 54165) - (UT2-UT1)
where A = 2*pi*(MJD-54160)/365.25 and C = 2*pi*(MJD-54160)/435.
TAI-UTC(MJD 54161) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54160)**0.80 S t = 0.00025 (MJD-54160)**0.75
