Coordinated Lunar Time (LTC) needed due to differing gravitational forces

Nasa is working to create a new standard of time for the Moon that will see clocks move faster than on Earth, according to a White House memo.

The US Office of Science and Technology Policy (OSTP) directed the US space agency to set up a moon-centric time reference system that accounts for its differing gravitational forces.

In a memo on Tuesday, OSTP chief Arati Prabhakar noted that Earth-based clocks would appear to lose 58.7 microseconds per Earth-day as a result of these factors.

Nasa has until 2026 to set up a unified time standard, which Ms Prabhakar referred to as Coordinated Lunar Time (LTC). It will then be used by astronauts, spacecraft and satellites that require highly accurate timekeeping.

What about just a measurement base time? we could have that for given points in space time (ST) that accounts for other bodies as well?

So earth is at a given apogee with other significant bodies (SBs) is one time zone

We just increase the measurement of SBs until all the given points of a related points of ST (PSTs) when controlled for the gravity of SBs have the same time within a give precession range.

Seems more scalable and better at accounting for the movement of SBs
