P K Seidelmann (ed.) (1992), 'Explanatory Supplement to the Astronomical Almanac', at p.42; also IAU Commission 4 (Ephemerides), Recommendations to IAU General Assembly 1976, Notes on Recommendation 5, note 2.

The 1991 definition refers to the scale agreeing with the SI second "on the geoid", i.e. close to mean sea level on Earth's surface, see IAU 1991 XXIst General Assembly (Buenos Aires) Resolutions, Resolution A.4 (Recommendation IV). A redefinition by resolution of the IAU 2000 24th General Assembly (Manchester), at Resolution B1.9, is in different terms intended for continuity and to come very close to the same standard.

原子時間尺度A1（TAIの前身）は、1958年1月1日の従来の開始日にUT2と等しく設定された（L Essen, "Time Scales", Metrologia, vol.4 (1968), 161-165, at 163を参照）。そのときのΔT (ET-UT)は約32秒であった。オフセットの32.184秒は、「現在の値に連続性を与え、暦表時の使用を実践する」ための、1976年の暦表時(ET)とTAIとの差の推定値である（IAU Commission 4 (Ephemerides), Recommendations to IAU General Assembly 1976, Notes on Recommendation 5, note 2を参照）
