These predictions were made using the JPL DE405 planetary and lunar ephemerides and include both nutations and librations (referred to the International Celestial Reference Frame). The value for Delta-T (the difference between Coordinated Universal Time and Terrestrial Time) on 2017 Jan 01 is 68.2 seconds. All calculations are by Fred Espenak, and he assumes full responsibility for their accuracy.
