 # OFFLINE NOTES:
 # - LVGL, the clock, touch and backlight operate locally.
 # - Home Assistant control buttons require an API connection.
-# - The clock continues using the most recently synchronised time.
+# - At boot, system time is restored from the battery-backed RX8130 RTC.
+# - When Home Assistant time synchronises, the corrected time is written back to the RTC.
+# - A suitable backup cell must be fitted for the RTC to retain time without panel power.
