Target-time countdown
The last 10 seconds are emphasized. Countdown is recalculated from the target timestamp instead of subtracting one second at a time.

Accuracy note: this page shows your device clock, not the ticketing site's server clock. For ticket releases, enable automatic date/time and time-zone sync on your device. Background tabs may also be throttled by the browser, so keep this page visible near the target time.
How the clock and countdown work
- The live clock reads Date.now() every animation frame and includes seconds plus milliseconds.
- Countdown is derived from target timestamp minus current timestamp, which avoids setInterval-style cumulative drift.
- Fullscreen and Screen Wake Lock depend on browser support and may require a user gesture.
- No selected target time is written to the URL, local storage, or Analytics.
