Gregory's Server@dgoldsmith You seem to be knowledgeable on this topic. Could you explain why we do not just compensate for gravitational red shift on the moon the same way we do for the various NMI labs that are at different altitudes and thus run at slightly different rates? Why do we need LTC when just using UTC with the correct definition of the second (i.e. defined at zero gravitational field) would be sufficient?

and in particular, the goals:
1. Traceability to Coordinated Universal Time (UTC);
2. Accuracy sufficient to support precision navigation and science;
3. Resilience to loss of contact with Earth; and
4. Scalability to space environments beyond the Earth-Moon system
It is still linked to UTC, as far as I can tell (bullet 1).
