Thanks
for the feedback Eric, I appreciate it.

I
spot-checked a few things, and thought you would like to
know:
- it
seems that the polygon for the south east corner of British Columbia is missing
(at least, I don't have it in OpenJump)
- I don't see the equivalent of the
Australia/Eucla timezone
- I think the Kwajelein timezone is at most the
Kwajelein atoll (and at least those islands of the atoll that are leased by the
US), and your zone seems to include islands from other atolls (Maloelap, Erikub,
Wotje,
Ailuk)
====================================================================
I
think everything is OK in the south east corner of British Columbia - how do you
spot it is missing? There are timezone shapes for Cranbrook (which is probably
what you refer to) and Creston, apart from Dawson Creek to the north-west, and
Lloydminster in the Saskatchewan area, all independent
timezones.
You
are right about Eucla. The city is there in World Time Explorer, with correct
timezone information, but I never created a shape for Eucla since I don't know
the extension of it. Do you have any authoritative info (or even
hear-say)?
The
Kwajalein question is interesting (as the teacher says when he doesn't know the
answer). I have no authoritative information about this, so it is quite probable
that you have found one or several errors. Wikipedia divides the Marshall
Islands in the Ratak Chain (Sunrise Eastern) and Ralik Chain (Sunset, Western).
Majuro is part of the former, and Kwajalein of the latter, but I'm not sure if
geographic/administrative regions can be directly related to timezones, so that
everything in one Chain belongs to that timezone (that would certainly be an
easy solution, probably too easy). In that case you are right that Maloelap,
Erikub, Wotje, Ailuk all should belong to the Majuro timezone - it would also
mean the following additional changes
From
Majuro timezone to Kwajalein timezone: Ailingalap, Namorik, Jabwot, Namu,
From
Kwajalein timezone to Majuro timezone: Bikar.

You may want to check the licensing
terms of your source data. I don't really understand the practices for maps, but
I suspect your map is a derived work, and that you don't have complete freedom
for the licensing
terms.
====================================================================
You might be right about this. At least the base world map was part of
the ESRI shapefile collection, and thus have a license attached, so that derived
works can be made and used, but would not give complete licensing freedom. I
think I have worked quite a lot to create added (timezone) value to the map, but
the consideration exists.
