About itime.day

itime.day is a precise, calm, developer-friendly time companion. The first version focuses on a trustworthy online clock, Unix timestamp conversion, cron previews, and timezone boards.

The clock estimates the difference between your browser clock and the nearest edge endpoint by taking several samples, filtering for lower round-trip time, and showing the estimated offset. It is not an official time source and should not be treated as a replacement for NTP/PTP in production infrastructure.

Accuracy depends on network conditions, proxy routing, browser privacy protections, device load, and whether the tab has been suspended in the background. That is why the product shows confidence and offset instead of promising impossible “0ms accuracy”.
