·the European Space Agency (ESA) has proposed establishing a new time zone on the moon...
It already has one. It's called Zulu.

·I'd go. I'd take a dozen Speedmasters, so I could keep one for myself and sell the rest as moon-worn! I'm sure it would pay for the trip.

UTC is an Earth based time standard …..The International Earth Rotation and Reference Systems Service (IERS) tracks and publishes the difference between UTC and Universal Time, DUT1 = UT1 − UTC, and introduces discontinuities into UTC to keep DUT1 in the interval (−0.9 s, +0.9 s)
So in principle they do need to explore an applicable time standard for other bodies with different day lengths. I think other gravitational and velocity factors also impact the speed of clocks which need to be factored in for very precise calculations and timings.

·But people are used to 24-hour days even when people go to the moon. A day 27 and a bit earth days long would not be useful for people who need to sleep 8 hours out of every 24.

·Do you envision the robots being controlled (or maybe directed would be a better word) from Earth? Then maybe adopting the time zone of wherever the controllers live

I guess UTC would or could remain the time standard datum point. I think they are talking about a new common time zone which might be more relevant to people and devices operating on or around the moon. One assumes that would be relatable to UTC in some way and also to other time zones (a bit like when we travel around down here). There are more physical variables given the distance, changes in gravity, velocity and orbits etc. I don’t know to what degree that will impact the comparable accuracy of multiple identical clocks on earth and the moon. I also don’t now how critical any minor creeping difference might be. We already have leap seconds on earth so one assumes there would be similar but different corrections needed for other bodies and orbits. I think I will be adopting Luny time soon if I think about the topic any further :0)

·For Mars, the controllers of landers and rovers use Mars time. The rovers would work during the day carrying out their program while the sun shines on their solar panels. Then radio back in the evening. The controllers on earth then needed to check what the rover did during the day and write up its instructions for the next day in time to radio them back. A Mars day is 24 hours and 40 minutes, so the schedule shifts a bit each Earth day, and the controllers have a very cramped social life for the duration of their time on the controlling team.

Do the controllers have "Mars Time" watches? Another rabbit hole for collectors...

Mars time watches do exist. One obvious one is the Omega X-33 Marstimer edition. (If nothing else at least it's a special edition that actually does something really special!) I don't know if they were issued to the controllers or if they had to buy them themselves if they wanted one.

·one benefit from being in outer space and on the moon is that you get taller bec. the spine lengthens.
for us taller peeps, that is quite a benefit and fewer back problems!

·There's no lack of interest going to the Moon, since 2012 China has been training a dozen female military pilots aiming for a lunar mission putting the first woman on the Moon by the end of this decade ! Taikonauts to the Moon !
