Of all the files I did not look at this one. Please forgive and thank you very much. Now if I only knew where the boundaries are..

You can then traverse the links to get a mapping back from all the zones to countries. CLDR keeps such an updated mapping in http://www.unicode.org/cldr/data/common/supplemental/supplementalData.xml (Search for zoneFormatting. 001 is the UN M.49 code for "the world", and is given to the Etc zones. Etc/Unknown is a CLDR addition that is used where the zone is invalid or unknown.)

Some are simple i.e. the rule name matches the country, but there are some like C-Eur where an additional list is required to understand which countries are included in the time zone. Thank you very much for your help.
