The sequence of dates of the UTC second markers will be: 2005 December 31, 23h 59m 59s 2005 December 31, 23h 59m 60s 2006 January 1, 0h 0m 0s The difference between UTC and the International Atomic Time (TAI) is: from 1999 January 1, 0h UTC, to 2006 January 1 0h UTC : UTC-TAI = - 32s from 2006 January 1, 0h UTC, until further notice : UTC-TAI = - 33s ************************************************************************** Important Notice - IAU 2000 Resolution Compliancy Information ************************************************************************** Resolutions passed at the 24th General Assembly of the International Astronomical Union (IAU) recommend the implementation of a number of new procedures concerning the transformation between the celestial and terrestrial reference systems. Information regarding these procedures is available in Chapter 5 of the IERS Conventions 2003 available at . With these resolutions, beginning on 1 January 2003, IERS Bulletins A and B will publish new products in addition to those already published. These products will include the celestial pole offsets X_obs-X_IAU2000A and Y_obs-Y_IAU2000A where X_obs and Y_obs are the observed X, Y coordinates of the Celestial Intermediate Pole in the Geocentric Celestial Reference System, and X_IAU2000A and Y_IAU2000A are the celestial pole coordinates provided by using the IAU2000A Precession-Nutation theory. It is expected that Celestial Pole offsets related to the IAU1980 Nutation Theory will continue to be published through 15 January 2006. The new celestial pole offsets related to the new IAU2000A Precession-Nutation theory will be produced in a separate data file as well as appended to to this file. ************************************************************************** Important Notice - IAU 2000 Resolution Compliancy Information **************************************************************************
