From: Tom Lane Date: Sun, 2 Aug 2026 15:26:30 +0000 (-0400) Subject: Update time zone data files to tzdata release 2026c. X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6ca405938d4d65d1979460421ac3327a98a42d44;p=thirdparty%2Fpostgresql.git Update time zone data files to tzdata release 2026c. Alberta (America/Edmonton) moved to permanent UTC-06 on 2026-06-18, which will affect their clocks beginning on 2026-11-01. For lack of any clarity on the point, assume their TZ abbreviation will be CST from that time forward. Morocco (Africa/Casablanca) will move to permanent UTC+00, without daylight saving time transitions, on 2026-09-20.
