From 1c16d1187c66395cc1d567f3d951ad26bead9138 Mon Sep 17 00:00:00 2001 From: "jampick@microsoft.com" Date: Sat, 18 Apr 2026 22:19:14 -0700 Subject: [PATCH] fix: add timezone selector to quiet hours in web UI The quiet hours section showed timezone as static read-only text (system local only). Users had no way to choose a different timezone, so quiet hours always fired against the Pi's local clock. Changes: - pi/appliance.py: add quiet_tz="" to default_config() - pi/webapp/server.py: add SELECTABLE_TIMEZONES list; validate and save quiet_tz from the form; pass timezones= to both render_template calls; update _quiet_hours_active() to use configured tz via zoneinfo - pi/webapp/templates/index.html: replace static "Timezone: {{ timezone }}" help text with a + {% for tz in timezones %} + + {% endfor %} + +

Printer stays silent between these hours. Timezone: {{ timezone }}
