Geographical timezones cover the Earth in such a way that two timezones never overlap; hence, they are non-overlapping. But is there a better (shorter, without negation) word for this?
"Unfortunately he's travelling, possibly to a non-overlapping
timezone, so I'm not sure when he can take the call."
Distinct and discrete come to mind, but they miss the nuance of continuously covering a surface and would not work in the sentence above (although just plain old different would).
Best Answer
The timezones partition the globe (planet). That means that they do not overlap, that they are contiguous, and that they cover the entire globe.
