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

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 = .0507 - .0847 cos A - .0484 sin A - .0963 cos C + .0249 sin C
y = .3525 - .0487 cos A + .0787 sin A + .0249 cos C + .0963 sin C
UT1-UTC = -.3086 - .00085 (MJD - 54504) - (UT2-UT1)
where A = 2*pi*(MJD-54496)/365.25 and C = 2*pi*(MJD-54496)/435.
TAI-UTC(MJD 54497) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54496)**0.80 S t = 0.00025 (MJD-54496)**0.75
