So good luck with that...
Defining lunar time is not simple:
Although the definition of the second is the same everywhere, the special theory of relativity dictates that clocks tick slower in stronger gravitational fields. The Moon's gravitational pull is weaker than Earth's, meaning that, to an observer on Earth, a lunar clock would run faster than an Earth one. Gramling estimates that a lunar clock would gain about 56 microseconds over 24 hours. Compared with one on Earth, a clock's speed would also subtly change depending on its position on the lunar surface, because of the Moon's rotation, says Tavella. "This is a paradise for experts in relativity, because you have to take into account so many things," she adds.
Previously, previously, previously, previously, previously, previously, previously.
The tides at the beach are telling us that neither do atomic chronometers on the surface of the earth always tick at the same rate.
They do always tick at the same rate. It's just that the curves they follow through spacetime have different lengths.
That sounds like nitpicking but it's not: clocks whose timekeeping is controlled by gravity (which really means pendulum clocks) have rates which do vary as the local gravitational field varies, while atomic clocks don't (or, well, they probably do but you'd only be able to notice if you were in some field where tidal effects are a big deal on atomic scales, which probably means close to the event horizon of a (small) black hole).
This sounds like the crew of general relativists who spent 4 decades complaining that the way JPL was interpreting the relativity, coordinate systems, and doing the ephemeris integrations was wrong. That argument ended after this Curiosity entry image https://www.nasa.gov/mission_pages/msl/multimedia/pia15978b.html
It may sound like that but it's not: that really is who time works in GR (and we have no theories better than GR, and any better theory will almost certainly have to be compatible with GR in the appropriate limits).
Why don't we just start with the CVE's we'd like to see from this.
Then we can work backwards to build the appropriate moontime libraries needed to trigger them.
Given that there is a sizable contingent of people taking the position of "leap seconds are weird, let's just get rid of them, yolo" I don't think that's going to go very well.
I am looking forward to hearing about the timely death of the first manned Mars mission along with both the CEO and the entire cargo of indentured slave fan boys when the ship plummets into the Martian surface due to missing leap seconds and relativistic time corrections in the “totally hardcore” flight guidance software.
We've already sent things safely to mars ...
Yes, but what's more useful to humanity to land safely on Mars, a robot, or a billionaire?
Hard to say! Let's send a couple dozen of each and see which one lasts longest.
As long as we don't have to bring them back.
Let's not. It's almost inconceivable that billionaires and their slave crews can be made sterile enough not to seriously fuck with our chances of knowing if Mars has life. Of course plutocrats don't care about that: the only life they care about is their own.
I propose instead that we encourage them to aim at the Sun. It's unfortunate that the huge delta v requirement makes landing on the Sun much harder than Mars. But I am sure they will be up to the challenge.
Pfft. To this day, only the Soviets have landed a craft on Venus. I feel like we should take Venus back with a manned mission as you suggest.
A Nasa Pioneer probe accidentally operated for 45 minutes on the surface of Venus.
A. As many billionaires as possible.
There are a disturbing number of brogrammers who think time zones are too hard and we shouldn’t have them.

TZs are indeed hard. Everyone who can leverage an existing maintained TZ package should leverage reuse and avoid coding anew.
The difficulty of TZs isn't technical. Instead it is a matter of discovering and implementing constantly changing requirements. When any government agency, even one subordinate to the national sovereign, can change their rules at any time and announce their change via their own chosen official channels (which might not even involve publication on the internet) then finding about the recent TZ changes can be quite an Easter egg hunt.
That would be the general theory of relativity, not the special theory. Special relativity says nothing about gravity.
Not remotely an important point, but you'd hope for better attention to scientific detail from this particular venue.
Both special and general relativity have to be taken into account to make GPS work. For the curious, see details at https://www.astronomy.ohio-state.edu/pogge.1/Ast162/Unit5/gps.html
This is probably going to drive the tzlist denizens nuts.
