>"OSTP chief Arati Prabhakar's memo said that for a person on the moon, an Earth-based clock would appear to lose on average 58.7 microseconds per Earth-day and come with other periodic variations that would further drift moon time from Earth time,"

While there are relativistic (and other) effects which would cause physical clocks to differ, the second is defined in terms which exclude those ("unperturbed"). So there is no validity to the claim - the second is deliberately defined to be invariant (to the best of our knowledge), and physical clocks are corrected for such errors. For example, adjustments are already made for GPS satellites, which experience similar effects. Seconds tick at exactly the same rate everywhere.
