tai_from_tt

spacekernel.time.tai_from_tt(jd12_tt: ndarray[double]) → ndarray[double]

Convert two‐part Julian Dates from TT (Terrestrial Time) to TAI (Atomic Time).

Parameters:

jd12_ttndarray of float, shape (N, 2)

Two-part Julian Date entries in the TT timescale.

Returns:

jd12_taindarray of float, shape (N, 2)

Two-part Julian Date entries in the TAI timescale.

Notes

Internally dispatches to the low-level C routine c_tai_from_tt for each row, preserving full double-precision accuracy.
