World Clock Wallboards

Why wallboards still matter

Ops rooms, broadcast trucks, and pubs need a glanceable view of multiple cities. Laptop clocks are personal, and “world time” widgets drift or hide behind paywalls. The TimeyKit World Clock renders a clean grid that handles DST and runs on any TV with a browser, so the whole room shares the same truth.

Setup checklist

Hardware

• Spare monitor or TV with HDMI input.
• Low-power device (Intel NUC, Raspberry Pi, Chromebox) running a modern browser in kiosk mode.
• Reliable network so the wallboard can fetch fresh timezone rules when reloads happen.

Software

1. Open timeykit.com/world-clock/.
2. Add the cities or teams you care about. We recommend no more than 8 per display.
3. Toggle the fullscreen/wallboard mode and hide controls for a clean look.
4. Bookmark the resulting URL so it reopens after power failures.

Example layouts

Control room

Columns: UTC, Production HQ, On-air city, Engineering vendor. Highlight the show window and keep a UTC row for satellite coordination.

Pub or bar showing WC26 fixtures

Run the WC26 wallboard on one tab and the World Clock on another with host city plus top tourist origins. Patrons instantly know when the next match lands in their hometown.

Operational tips

• Schedule a weekly auto-refresh so tzdata stays current.
• Sync the device clock via NTP; a wrong OS time defeats the point.
• Use “copy link” and stash it in your runbook so rebuilds take seconds.

Maintenance log template

Track when you last checked the wallboard. A lightweight log might include columns for “Date,” “Who verified,” “Cities shown,” and “Notes” (e.g., “Added Auckland for visiting execs”). Reviewing the log monthly keeps someone accountable for refreshing the device, clearing cookies, or swapping in new cities before major events. Include a reminder to open the World Clock tool on a laptop to confirm the kiosk matches the reference layout before signing off.

FAQ

Does the wallboard cache data?

It runs client-side, so it keeps ticking even if the network drops temporarily. Reload when back online to pull any tzdata updates.

Can I brand the display?

You can use the built-in accent colors per row. For deeper customization fork the repo, but keep updates in sync with upstream timezone data.

How many cities is too many?

Past ten rows the display gets crowded. Split across two screens or rotate between playlists.
