Please refer to the website: http://tai.bipm.org/iers/convupdt/convupdt_c10.html The main changes, thanks to the efforts of U. Hugentobler, J. Kouba, S. Klioner, J. Ries, and G. Petit are: * New definition of TDB following IAU Resolution B3 (2006) and correspondingly new description of the relations between time scales. * New section "Transformation between proper time and coordinate time in the vicinity of the Earth", including effects and conventions relevant to GNSS clocks. * Numerical examples for the relativistic terms in the acceleration of an Earth's satellite.
