For countries with a single timezone, you can look it up by iso3166 two character code in %DateTime::TimeZone::Catalog::ZONES_BY_COUNTRY. For other countries, I don't know of such support. You can read the comments in zone.tab or the longer comments in the region files in the tzdata package at ftp://elsie.nci.nih.gov/pub/.
