<div class="gmail_extra">In theory, yes, that is my
understanding. Of course, in international waters, the zone
that "correctly" represents the local rules would be, e.g.,
Etc/GMT-3, but in general, if an existing set of rules does
not properly cover a region (for all timepoints since 1970), a
new zone is to be created.<br>

<div class="gmail_extra">The tz project neither defines nor
tracks zone boundaries; however, it is sometimes helpful to
think of zones in this manner. Obviously such boundaries
would change upon the creation of a new zone. You could make
the case that such boundaries would also change if it is
discovered at some point that location A better matches zone X
than zone Y, but as long as location A is not itself defined
in zone.tab, this does not affect tz data, and thus does not
concern the tz project beyond documenting appropriate
commentary.<br>
