-# WayVR GUI Customization

-When customizing the watch, keyboard, dashboard, etc; place custom XML files under ~/.config/wlxoverlay/theme/gui
-
-## Custom timezones, 12 vs 24-hour clock
-
-These are not done via the GUI system, but via the regular config.
-
-Create `~/.config/wlxoverlay/conf.d/clock.yaml` as such:
-
-```yaml
-timezones:
-- "Europe/Oslo"
-- "America/New_York"
-
-clock_12h: false
-```
-
-Once this file is created, the various settings in custom UI that accept the `_timezone` property will use these custom alternate timezones (instead of the default set, which are selected as major ones on different continents from your current actual timezone).
-
-The first timezone is selected with `_timezone="0"`, the second with `_timezone="1"`, and so on.
-
-There is usually no need to specify your own local timezone in here; omitting `_timezone` from a `_source="clock"` Label will display local time.
