DT:TZ intentionally doesn't support them. It's not aiming to provide precisely the semantics of the Olson database, and you'll see they're not listed in DT:TZ:Catalog. If you want to resolve zone names exactly as in the Olson database, use DateTime::TimeZone::Olson (a separate distribution). If you want timezones of fixed offset, prefer DateTime::TimeZone::OffsetOnly over the Olson Etc/ names. -zefram
