Central European Time is the English localization of various EU and North African UTC+1 time zones and CET the abbreviation, all of which are referred to as time zones in common usage, and by some computer systems and applications. A time zone is a region on the Earth's surface, as any dictionary tells us; but "Central European Time" is not a region but (an English name for) a measure of time used in one of these time zones.
Strictly speaking what I called time zones are labels, as are the tzdb paths; it may also be used to refer to the areas in standard geographical longitudes; legalislatively, they are whatever the politicians tell us. Here, a time zone is a set of communities observing the same rules for timekeeping historically, or since 1970; the communities need not be contiguous, nor in the same country, in recent releases.
Exact wording helps (not only) when you want to make a point with a legislative body.
Communication for common understanding by others with no technical background is the goal. Defined exact wording would be desirable in legislation. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
