Clock accuracy
Check whether your computer, phone, or browser clock is fast, slow, or aligned with livetime.io edge time.
Device offset
Compare this browser against livetime.io edge server time.
livetime.io sends several uncached requests to a Cloudflare edge endpoint, records the browser send and receive times, and compares the midpoint with the server timestamp returned by the endpoint.
The final result uses the median offset from the lowest-latency samples, which reduces the effect of short network spikes.
Under 250 ms is effectively aligned for normal web use. One second or more can make logins, two-factor codes, meetings, scheduling, and debugging timestamps feel inconsistent.
This is a practical web clock check, not an official atomic-time certificate. Network latency and browser scheduling can still affect the estimate.
Turn on automatic date and time in your operating system, confirm the selected time zone, then rerun the check. If the offset returns, your device may be blocked from its normal network time source.
