TT(BIPM95) is a realization of Terrestrial Time as defined by Recommendation IV of Resolution A4 of the International Astronomical Union, adopted at its XXIst General Assembly (1991). Thus the unit of measurement of TT(BIPM95) is chosen to agree with the SI second on the geoid and its origin is defined by the following relation to TAI : TT(BIPM95) = TAI + 32.184 s on 1977 January 1st, 0 h TAI. TT(BIPM95) has been established according to the same principles as the previous versions (Guinot, B., Atomic time scales for pulsar studies and other demanding applications, Astron. Astrophys., 192, 1988, pp. 370-373). The difference TT(BIPM95)-TT(BIPM94) is less than 4 nanoseconds until MJD=48819 (1992 July 16). The largest discrepancy between TT(BIPM95) and TT(BIPM94) is 36 ns for MJD=49469 (1994 April 27). 1st column : MJD at 0 h UTC 2nd " : TT(BIPM95) - EAL - 32.184 s, unit is one microsecond 3rd " :
