Sobre Nós

What-Time-Is.info is a free, precision world clock designed for remote teams, international travelers, developers, and anyone who needs to know the exact time anywhere on Earth — right now.

Our Mission

In a globally connected world, coordinating across time zones is one of the most common daily challenges. Whether you are scheduling a video call with a colleague in Tokyo, planning a trip to New York, or debugging a server log in UTC, knowing the precise local time is essential.

Our mission is simple: provide the most accurate, fast, and clean time information for every major city on the planet — with zero friction. No sign-ups. No apps to install. Just open the page and see the time.

Technology

What-Time-Is.info uses a client-server synchronization technique inspired by the NTP (Network Time Protocol) standard. When you load the site, your browser measures the round-trip latency to our server and compensates for it, delivering atomic-precision time directly in your browser without any plugin.

Time data is updated every second using the browser's requestAnimationFrame API for smooth, accurate rendering. Timezone conversions are handled by the Luxon library, which leverages the IANA timezone database to correctly handle Daylight Saving Time (DST) transitions worldwide.

Who Uses This Site

What-Time-Is.info is used by software engineers checking UTC timestamps, project managers scheduling international meetings, journalists tracking breaking news across time zones, flight crews planning layovers, and students studying abroad who want to stay in touch with home.

We built this tool because we needed it ourselves — and we believe great utility tools should be free, fast, and available to everyone.
