About Time.is
Exact time for any time zone — synchronized directly with the global atomic clock network.
Mission and accuracy
Time.is exists to be the fastest and most trustworthy source of exact time on the internet. The displayed instant is synchronized with stratum-1 atomic clock sources, and round-trip network latency is measured and compensated for, which usually keeps the displayed error under 0.02–0.05 seconds.
7+ million places
The complete IANA time zone database, covering every country, territory, city and town on the planet.
Atomic synchronization
A latency-estimating clock algorithm keeps the seconds moving smoothly, without stutter and without ever running backwards.
High performance
A fast architecture built on a Go backend, giving instant page loads and minimal battery use on mobile devices.
58 languages
Localized for a global audience, with calendars and time formats that follow local convention.
