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 11 April 2013 at 0000 UTC
Beginning 1 July 2012:
TAI-UTC = 35.000 000 seconds

The contributed observations used in the preparation of this Bulletin
are available at <http://www.usno.navy.mil/USNO/earth-orientation/
eo-info/general/input-data>. The 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 = 0.0947 - 0.0667 cos A + 0.1283 sin A + 0.0560 cos C - 0.0546 sin C
y = 0.3405 + 0.1110 cos A + 0.0597 sin A - 0.0546 cos C - 0.0560 sin C
UT1-UTC = 0.1207 - 0.00098 (MJD - 56429) - (UT2-UT1)
where A = 2*pi*(MJD-56421)/365.25 and C = 2*pi*(MJD-56421)/435.
TAI-UTC(MJD 56422) = 35.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-56421)**0.80 S t = 0.00025 (MJD-56421)**0.75
