1991年在阿根廷布宜诺斯艾利斯举行的国际天文联合会(IAU)大会上，引入了地球时(TT)来代替地球动力时(TDT)，并引入了地心坐标时间(TCG)和重心坐标时间(TCB)这两个术语(IAU 1992)。将介绍这些时间类论点的原因及其应用。不同的类时间变元之间的关系将被讨论，以及它们的应用和与天文常数的关系
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
