From ed0aff98da0938d196076d964c915b5934be036f Mon Sep 17 00:00:00 2001 From: Tim Parenti Date: Sat, 22 Mar 2025 16:11:53 -0400 Subject: [PATCH] Improve recent commentary for Chilean decrees * southamerica (America/Coyhaique): Use publication date in UNTIL field for 2025 change, as we did with America/Punta_Arenas in 2016. (Chile): Update links to Chilean decrees since 2014 and lightly clean up related commentary. Remove some outdated "assume ... indefinite" comments that didn't ultimately pan out.
