Yeah knew about gps satellite time needing to be adjusted, I seem to recall some tens of microseconds per day. Wonder what the difference is on the moon.

Ground level on the moon is about ~56 microseconds per Earth day shorter than ground level on Earth, IIRC.

Ong said 66 microseconds, which is close enough for my poor memory to accept.
