What does the server clock tell you?
The site clock may differ from your device clock. Estimates here use second-resolution HTTP Date headers and RTT compensation, not direct access to the booking system clock. Millisecond display does not guarantee millisecond accuracy or a successful booking.

- Choose the site you want to check.
- Check the offset, measurement time, RTT and uncertainty. Do not rely on unavailable or stale measurements.
- Try the click timing practice tool.
- Follow the target site’s official opening time and instructions.
