Indeed so... I was always under the impression that it was just the "space jockeys" that generally lived by Zuran time, the Terrans being the obvious exception (damn the vile Xenos and their heretical time scales.

) In fact we hear so little about life on the planets of the X-universe that I'm generally led to assume the Spacers and the Planetsiders don't see much of each other. So each planet would probably adopt a timescale loosely adapted from their homeworld's- I suppose a stazura on Seizewell is not a stazura on Ceo's Buckzoid, and neither of these stazuras equals the galactic standard stazura. Similarly, an hour on Argon Prime is probably not an hour on Earth, but they're both still called hours.
^--- basically what I'm saying is, each planet probably has its own timescales unique to that planet's day/night and seasonal cycle. But an Argon will still call a "day" on Argon Prime a "day," and a Teladi will still call a "tazura" on Ceo's Buckzoid a "tazura."
However, even planetsiders would probably want to keep track of the Galactic Standard year/jazura. They'd probably keep track of their own months/mazuras for the sake of tracking the seasons of their planet and other such things, but their own planet's year/jazura would be less meaningful to them than that of their homeworld and of the galactic community.
And it's probably fair to say that the Boron, Split, and Paranid have their own timescales that are never discussed in space- if all five races had to communicate with each other without a standardized set of timescales (or any standardized measures for that matter) it would most certainly lead to only one race left standing.

So they'd agree on a timescale that's the most meaningful in their universe, but on their own planets they'd probably still run on their native scales.
This is all quite an interesting exercise in how frustrating the colonization of space can become.

Especially when you factor in diplomacy with alien species. And we haven't even touched on language barriers, variable diets, differences in atmosphere/climate, alien pathogens... third genders...
