Optional network layer
This page is prepared for a tiny Cloudflare Worker accuracy endpoint. Until that endpoint is connected, it does not claim atomic-time verification.

Main clock is still browser-only.
Honest accuracy policy
The homepage displays your device time with auto-resync. Official accuracy depends on your operating system time synchronization. A future Worker can compare your device clock with network time using a few quick requests, not one request every second.
About this time tool
Live Clock. See your exact local time with seconds in a clean live clock. Use fullscreen mode, watch sync, UTC, 24-hour time, world clocks, and offline app mode.
- The main interface is available in the initial static HTML, not only after JavaScript runs.
- The live clock uses your browser and device time zone support.
- No account, GPS permission, or external time API is required for the core display.
Frequently asked questions
What is accuracy sync?
This page explains an optional network-based clock accuracy check for the future.
Does the main clock need a server?
No. The main TimeWithSeconds clock stays browser-only and static.
Why not claim atomic accuracy now?
Because without a network time comparison, the page can only display your device clock, not verify official atomic time.
