Why new time scales?
Abstract
At the International Astronomical Union (IAU) General Assembly in Buenos Aires, Argentina in 1991, the name Terrestrial Time (TT) was introduced to replace Terrestrial Dynamical Time (TDT) and the terminologies Geocentric Coordinate Time (TCG) and Barycentric Coordinate Time (TCB) were introduced (IAU 1992). The reasons for these time-like arguments and their applications will be presented. The relationships between the different time-like arguments will be discussed along with their applications and relationships to the astronomical constants.
