To me, the entire point of time zones is that different parts (zones) of the same celestial body can experience different clock times (simultaneously). If you have only one zone for the moon, then don't bother, I say. Preferably, zones should be related to the view (viewing angles) of other celestial bodies from each zone.
It's 1 second of out of sync every 48 years. Instruments communication (ndr light speed) travels 1 mile during that amount of time... yes gps and similar would be affected!
