and it isn't *quite* as explicit as I'd thought:
Each timezone typically corresponds to a geographical region that is smaller than a traditional time zone ...
Perhaps we should more explicitly state that "timezone" and "time zone" are different names for different things, with a "timezone" *not* corresponding to what most people think of as a "time zone".
I was hoping that the quoted phrase was enough for that, but perhaps not. Perhaps italicize or quote "timezone" and "time zone" in it? Or some other rewording?
The TZDB commentary doesn't use a name for the concept you're asking about, but I suppose "geographical timezone" would do.
Which concept is that? ApoY2k said
do you (or your peers on the tz project) consider a "timezone" to be inherently tied to the real-world geographical features they are used for, or is the word "timezone" in this context more broader understood as "any 'Zone' entry in the tzdb" - which would e.g. also denote "Etc/UTC" as a "real timezone".
Are you referring to the first concept - something that is "inherently tied to the real-world geographical features they are used for" - or the second concept, which sounds like a "timezone"?
The former.
Is the first concept a subset of timezones, restricted to those timezones that have a geographical definition rather than a more abstract definition such as "everything in UTC" for Etc/UTC?
Yes.
