It strikes me as surprising to imply that we don't have time-keeping standards for solar system exploration that take into account relativistic differences.
the CSPICE toolkit from JPL/NAIF has a bunch of routines to calculate local time, local time of arrival of events from other places (light cone, I suppose?), down to the nanosecond.

- nynx 2y agoThat code exists for calculating those things does not mean there are timekeeping standards that support them.
- jvanderbot 2y agoTrue, should have mentioned (as sibling comment did) that the code _uses_ several timekeeping standards to do those calculations.
- zokier 2y agoThere definitely are various timescales and standards that take relativity into account https://en.wikipedia.org/wiki/Barycentric_Coordinate_Time https://en.wikipedia.org/wiki/Barycentric_Coordinate_Time https://en.wikipedia.org/wiki/Ephemeris_time https://en.wikipedia.org/wiki/Ephemeris_time https://en.wikipedia.org/wiki/Coordinate_time https://en.wikipedia.org/wiki/Coordinate_time Etc
