nomarchy.system.autoTimezone (off by default): geoclue + automatic- timezoned drive /etc/localtime from your location, so travelling to another zone updates the Waybar clock on its own. Menu-driven, in-flake state (the night-light / keyboard philosophy): the flag is settings.autoTimezone in theme-state.json (git-tracked); a System-menu entry toggles it. Because it's a SYSTEM service — not a user unit it can start/stop instantly like night-light — the toggle (nomarchy-autotimezone, run in a terminal) writes the flag --no-switch then drives `sudo nixos-rebuild` (bakes the service + the time.timeZone override) plus `home-manager switch` (the Waybar-refresh watcher); both sides read the one flag. - modules/nixos/timezone.nix: parses settings.autoTimezone from nomarchy.system.stateFile (like Plymouth), gates geoclue2 + automatic-timezoned, and mkForce-nulls time.timeZone — automatic- timezoned sets it null at normal priority, which collides with the installer's static value (a hard eval error), so force wins and reverts cleanly when disabled. Ships the nomarchy-autotimezone toggle. - modules/home/timezone.nix: a tiny user service watching timedate1's change signal that reloads Waybar (SIGUSR2) on a real zone change, so the clock follows live (Waybar captures the zone at construction). Gated on the same flag via nomarchy.settings.autoTimezone. - rofi menu: "Auto timezone (on/off)" in the System submenu. - option + template example + ROADMAP entry; theme.nix seeds the flag. Eval-verified on (geoclue+daemon on, tz forced null over a static installer value, watcher present) and off (static tz intact, nothing extra); home + system both build green. Needs an on-hardware check (geoclue detection + the SIGUSR2 clock refresh aren't CI-testable). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Auto-timezone, home side: keep the Waybar clock in step with the system

# timezone. Waybar's clock module captures the zone once at construction, so a
|
|
# runtime timezone change (automatic-timezoned, nomarchy.system.autoTimezone)
|
|
# would NOT show until a relogin. A tiny watcher subscribes to timedate1's
|
|
# change signal and reloads Waybar (SIGUSR2 = the same reload theme-sync uses),
|
|
# so the clock follows your location live. Also catches a manual
|
|
# `timedatectl set-timezone`.
|
|
#
|
|
# Gated on the same in-flake flag the system side reads (settings.autoTimezone,
|
|
# exposed via nomarchy.settings) — so it only runs when the feature is on. The
|
|
# menu toggle (nomarchy-autotimezone) rebuilds both sides off that one flag.
