# World Clock

> Market-open-aware world clock covering major global exchanges — open/closed indicators, concurrent session visibility, and trading-hour overlaps.

The **World Clock** panel (internal id `world-clock`) is a market-aware clock — not just a timezone grid. Each entry shows the current local time for a major financial capital, the exchange code (NYSE, LSE, XETRA, HKEX, SGX, Tadawul, etc.), and whether that exchange is currently open based on its trading hours.

## What the panel shows

Rows for the 30 global market centres in `WORLD_CITIES` (`src/components/WorldClockPanel.ts:14-43`). Each row includes:

* **City + exchange label** — e.g. New York / NYSE, London / LSE, Tokyo / TSE, Riyadh / Tadawul.
* **Local time** — continuously updated.
* **Market open / closed indicator** — derived from each city's `marketOpen` / `marketClose` hours in the entry config.

The default coverage spans the Americas (New York, Chicago, São Paulo, Toronto, Mexico City), EMEA (London, Paris, Frankfurt, Zurich, Moscow, Istanbul), Middle East (Riyadh, Dubai), Asia-Pacific (Mumbai, Bangkok, Singapore, Hong Kong, Shanghai, Seoul, Tokyo), and Oceania (Sydney, Auckland).

Panel id is `world-clock`; canonical component is `src/components/WorldClockPanel.ts`. Title from i18n (config name: "World Clock").

## How you reach it

* **Cmd+K**: type *clock*, *time*, or an exchange code.
* **Availability by variant**: registered and enabled by default in the **full/geopolitical**, **tech**, **finance**, and **commodity** variants (all `priority: 2`). Not present in the happy variant. Source: `world-clock` entries in `FULL_PANELS`, `TECH_PANELS`, `FINANCE_PANELS`, `COMMODITY_PANELS` of `src/config/panels.ts`.

## Data sources

No external data — the panel runs locally. Time is computed from the browser clock using each city's IANA timezone (e.g. `America/New_York`, `Asia/Hong_Kong`). Exchange-open state is derived from the panel's built-in `marketOpen` / `marketClose` hours per city.

## Refresh cadence
