Can the lunar nav system time hack be arbitrary? As long as all the lunar sats agree that their lunar-surface command station's time is the One True Time, if it has some unknown and variable offset from GPS, why should lunar users care? ... Only _within_ the lunar nav system do you need nanosecond lock-in, don't you?

I believe that's correct. For bonus points, regularly determine the offset between GPS and LPS time, and include it in the LPS data stream.
