how to filter timezones within each country to drop those that as of today are not relevant except for historical differences?
For each country listed in zone.tab, if at least one of its timezones appear in zonenow.tab, drop its timezones that do not appear there. Although this won't be "perfect" it should be good enough (and opinions will differ about what is "perfect").
