From acf4b7b83933abf6ff53ee3c4664cbbf7a9adab1 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Wed, 22 Apr 2026 12:53:13 +1000 Subject: [PATCH 32/60] call tzset() before chroot to cache timezone data localtime/localtime_r need /etc/localtime for timezone info. After chroot this file is inaccessible, causing log timestamps to fall back to UTC. Calling tzset() before chroot ensures the timezone data is cached by glibc for subsequent calls.
