From review: EET and WET link to Athens and Lisbon but name clock rules, not Greece or Portugal, so they and the other rule names (CET, EST5EDT, …) send nothing. Pacific/Johnston has left zone.tab, which made its Honolulu group look only American; it's set to UM by hand. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
